New contacts not being saved

[BeMiGro]

I’m not totally sure, but I had a (maybe) similar issue with a DAVdroid account:

Cannot create new contact for non-Google account

When I try to create a new contact I cannot select an account anymore, the gmail.com account is preselected and cannot be changed. Before the MM update on Android 5.1 I could e.g select my Davdroid account I wanted to assign the new contact to. Am I missing something or can anybody approve this behavior?
