Profiles errors

I was using Kodi 16 with profiles, everything works fine.
Now I’m testing with Kodi 17 (RC2), profiles gives several problems. I’m using a fresh install of Kodi 17 RC2 on Windows and OSX. Both have the same problems.

– After creating profiles, can add skins in Master profile, but not in new profile (just returns without message)
– Changing menu settings in new profile causes strange settings (menu disapears, etc) in Master profile
– Setup up Add-Ons in new profile is not working (somethimes it will, somethimes it do’nt) in Master profile no problems.

I’ve tried several skins, but the problems seems not to be skin related.
