Decoding IntelliJ IDEA folder name colors

Question

I have project, that have 4 Git Roots: Project, Project-commons, Project-ui and Data Model.

Due to certain config, I need to put Project-commons, Project-ui and Data Model into Project dir. But this resulted in IDEA highlighting Project-commons, Project-ui and Data Model as red folders.

Git still works for me (as well as Maven), I didn't have any merge errors. What does that red highlight mean? Using "Synchronize" option to them helps, until I restart IDEA. I believe it has to do something with 3 Git roots inside another Git folder, but how do I fix it?

It looks like this:

My IDEA version is 14.1.
