after booting a device and logging in a user all policies are set (especially the user settings set over a ZCM GP-User assigned policy).
After the schedule "partial refresh schedule" one can see that the policies where successful applied again (in system tray app).

ALL (windows-grouppolicy-) policy settings assigned to the user where deleted and not available and no longeer applied to the system (after this "partial refresh")!
We can see that this settings are not in the registry and also not in the files under %WinSysDir%\GroupPolicy\
At both locations this settings are gone!

On systems with the ZCM Agent 2017.1 we can not see this problem.

Is this a known problem?
