Kivy FileChooser Overlapping

Question

I am using the FileChooserListView from kivy and have run into a overlapping text on scroll with screens that another user came across as well. I looked through their post on GitHub and read that some people are using the plyer FileChooser. I also saw that someone mentioned that it has to do with the Building function of the .kv file. I created a new kivy app and the problem did not occur, but when I return to my older app (no changes of any kind) the problem still occurs.

Sorry for the long post, but I am unsure how these two kivy app codes are different. Am I calling something twice that is causing the FileChooser to "hold" it's position? I am not oppose to using plyer's FileChooser, but could someone give me an example on how to implement it?

Answer 1

After taking a break from this for while and restarting my brain, I was able to find the problem.

Not included in my question, I have a couple more .kv files that have a similar layout to the training.kv. They are used to access other screens. I found that I was calling FileChooserListView in each screen and I belive that is why I was seeing the stacking problem. I ended up removing all of them except for the one in my training.kv file and all is working.
