I'm not sure what's going on but there is a project that has a folder "main" and "test" that don't show their subfolders / files in the Project View.
I believe this is due to some super-obscure-setting but I could not find it.
See screenshot attached.
Notice that I'm editing a file under the "main" folder and it does not expand to that file.
It's not even expandable.
The same doesn't happen to other projects.
Any idea why they don't show up?
