Kivy: Having trouble getting two Recycleviews to show up in my Kivy application

I'm working on a kivy application. I create two recycleViews, both pull data from a database table and I want the data to be displayed under the two recycleviews.
I've created the following .kv file:
#:kivy 2.1.0
<SelectableUserBoxLayout>:

These are the relevant Recycleviews:
class UserListView(RecycleView):
def __init__(self, **kwargs):
super(UserListView, self).__init__(**kwargs)
self.data = [{"userid": str(x[0]),"uniqueid": x[1], "displayname": str(x[2]), "status": str(x[3]), "permissionid": str(x[4]), "selected":False} for x in database.get_all_users()]
class ReservationListView(RecycleView):
def __init__(self, **kwargs):
super(ReservationListView, self).__init__(**kwargs)
self.data = [{"resid": str(x[0]),"startTime": x[1], "endTime": str(x[2]), "userId": str(x[3]), "lockerId": str(x[4]), "selected":False} for x in database.get_all_reservations()]
while the colums show correctly, the data under the colums aren't. To illustrate (mind that my application runs on a raspberry pi with a custom screen):
As you can see, my columns load correctly, and the first recycleview loads userdata from the database. The data, however isn't lined up properly. My second recycleview loads reservation data from the database. When I tap under the column, my screen shows data being clicked, but isn't displayed correctly in the recycleview.
My questions:
How can I get the data to line up correctly to my colums?
How can I get the data under my second column to be displayed correctly?
Edit: Seems like I've used SelectableUserBoxLayout twice. That explains a lot! I've rewritten my .kv file and it now works the way I want.
my new .kv file:

How can I make Spacing in BoxLayout?

I try to build a simple layout of widgets.
The BoxLayout includes three widgets: label and two anchorlayouts.
BoxLayout has a spacing parameter that is specified as "vertical".
So ... I don't see any spaces between the widgets inside the boxlayout.
enter image description here
There is kv:
<WellcomeScreen>:
wellcome_label: wellcome_user
BoxLayout:
orientation: 'vertical'
pos: self.parent.pos
size: self.parent.size
padding: [30, 30]
spacing: [10,10]
canvas.before:
Rectangle:
source: 'Data\game background.png'
pos: self.pos
size: self.size
ShadowLabel:
canvas.before:
Color:
rgba: .5,1,.7,1
Rectangle:
pos: self.pos
size: self.size
size_hint: (1, .6)
id: wellcome_user
font_size: self.height/16
text_size: self.width-10, None
markup: True
color: 'purple'
halign: "center"
AnchorLayout:
size_hint: (1,.1)
canvas.before:
Color:
rgba: 1,.5,0,1
Rectangle:
pos: self.pos
size: self.size
Button:
pos_hint: {"center_x":0.5,"center_y":0.5}
size_hint: (None,None)
size: (self.parent.height-5,self.parent.height-5)
background_normal: "Data\Button_sound.png"
AnchorLayout:
size_hint: (1,.3)
canvas.before:
Color:
rgba: .2,.7,.7,1
Rectangle:
pos: self.pos
size: self.size
Button:
canvas.before:
Rectangle:
source: "Data\Button_start.png"
pos: self.pos
size: self.size
pos_hint: {"center_x":0.5,"center_y":0.5}
size_hint: (None, None)
size: (self.parent.height/4*3, self.parent.height/4*3)
background_color: (1,1,1,0)
font_size: self.height/4
text_size: self.width, None
text: "START"
color: "yellow"
bold: True
halign: 'center'
on_press:
root.manager.transition.direction = 'left'
root.manager.current = 'login'

According to the documentation, the spacing is a number, not a list of numbers. Try changing:
spacing: [10,10]
to:
spacing: 10

kivy multiple instances of a screen with unique data

good day
is it possible to have multiple instances of a screen each using unique data? for example, i have a 'homescreen' with various buttons for various categories that takes you to a batch list screen unique to that category where you can add batches to be listed. each buttons batch list screen would have unique data to that category but the template for all batch list screens are the same.
ive made a simple example for one category but in order to expand it to the others would i need to repeat the code and create appropriately named .kv files and add each screen to the screen manager.

As this is a lot of code you will have a hard time finding someone to give you a specific answer. Without looking through all of your code, yes it is possible to have multiple instances of a screen with unique data. This is exactly the use case of class instances. You simply need to pass a variable, list or object into the instance. I will give you a short example, then you should be able to figure it out yourself for your code.
class MyReusableScreen(Screen):
def __init__(self, data, **kwargs):
super(MyReusableScreen, self).__init__(**kwargs)
self.data = data
mylabel = Label(text=self.data['mylabel_text'])
We added the attribute data to the class. Now we have to pass the data when we initialize the class instance
data1 = {'mylabel_text': 'first label'}
data2 = {'mylabel_text': 'second label'}
screen1 = MyReusableScreen(data=data1)
screen2 = MyReusableScreen(data=data2)
Like this we added unique label texts to the class instances labels. I guess you should now be able to build it up on your own. In case you defined a label in kv language, give it an id like for exanple id: mylabel and then assign the data value like this within you screen mylabel.text = self.data['mylabel_text']. I hope this helps you and if you struggle with something just give me a sign.

How to Dynamically add a button from the .py file to a single screen of a screen manager in .kv file

How can I dynamically add a button to a particular screen of my .kv file's screenmanager? The problem is, the buttons that get created show up on all screens.
I have a program I am working on that will allow the user to input there particular conditions and calculate ACFM. I am currently trying to set up a file screen that allows the user to create multiple files. I am trying to allow one main button called "create new file" creates more buttons on the first screen. The problem is, the buttons that get created show up on all screens.

I am not getting any error messages. I just want the dynamically created buttons from the .py file to only go to one screen of the .kv file.

You are currently adding it to the Calc FloatLayout which is the root and each screen is a child of this root. If you want to add it to just one screen, than you need to call the add_widgets function of that specific screen.
One option is via an id
change kv file like below
Screen:
id: id_solverscreen
name: "solverscreen"
change py file like below

Issues with refreshing kivy widgets

I'm having issues with refreshing a BoxLayout of widgets by removing them and then rebuilding the widgets based on the list 'Groups'. When on the EditDeviceGroups screen, the 'create' button should add an element to the list and forward the user to the GroupTemplateScreen, which it does.
The issue occurs when the user uses the back button to return to the EditDeviceGroups screen. At that point, I thought the on_enter method would refresh the widgets to include the new element, but the list shows no changes.
I assume it's some sort of issue with classes and instances, but I cant quite see around this one as this is my first real attempt with Kivy.

#Problem#
The EditDeviceGroups screen is not refreshed with the newly added widgets because when the Back button is pressed, another instance of EditDeviceGroupScreen was instantiated.
#Solution#
With the following changes, when the user clicked the back button to return to the EditDeviceGroups screen, the on_enter method refreshed the widgets to include the new element added. Please refer to the example and output for details.
##soundclout.kv##
Deleted #:import main soundclout
Replaced main.EditDeviceGroupsScreen().create_group() with root.create_group()
##soundclout.py##
Replace all occurrence of EditDeviceGroupsScreen(). with self.
