Android studio suddenly shows full folder names, how to change

Android Studio suddenly shows the full name a folder in the Project view and I don't know how to change it. I tried to change the view with the settings in the option menu in the Project view (flatten packages check/uncheck, compact empty middle packages check/uncheck), but it didn't change.

This is how my project view used to look like:

This is how it looks now:

It seems to me that every folder inside the myapp folder suddenly has the full appid + its own name as foldername. I tried resetting Android Studio settings by using these commands (I'm a mac user):

rm -Rf ~/Library/Preferences/AndroidStudio*
rm ~/Library/Preferences/com.google.android.studio.plist
rm -Rf ~/Library/Application\ Support/AndroidStudio*
rm -Rf ~/Library/Logs/AndroidStudio*
rm -Rf ~/Library/Caches/AndroidStudio*

Still no changes. My current Android Studio version is Android Studio 2.2, build number AI-145.3276617.

The only thing I did was to update to the latest stable Android 2.2 version yesterday, I don't know if this changed the way the app appears, another project (the how it used to be screenshot) didn't seem affected at all.

This seems to be an issue with the newest stable 2.2 build. I reported the issue here, no response yet: https://code.google.com/p/android/issues/detail?id=223389
