Cannot move file to folder in git

Hello,

I have an AppCode project set up with Git, working fine checking in out, creating files etc.

However, most of my folders are, for some reason, greyed out, and when i try to drag them there, there's a red border around the folder, and nothing happens when i drop the file.

Is there anything i can do to fix this?

As a sidenote - would be nice with some sort of error message rather than just a silent fail.


See attached screenshot of how the folder looks greyed out.
