Wasn't sure why toggles kept getting activated while navigating the UI - until I found this bug above.
Made some ugly fixes to the code to prevent the background map toggles from activating while navigating the UI, which caused the background image to disappear.
If this problem keeps happening in the project, consider downgrading to Unity version 2018.3.14f1.
I might do so as well if problems keep popping up, but for now the program seems stable in the 2019 version.
