i have a problem with the zcm policies.

i created a windows group policie on my windows server. In this gpo only user settings are set (some registry keys with the new GPP feature on windows server 2008 R2). i didnt assign this gpo to any OU.
All my clients can "understand" the new GPP policies.
Then i created a zcm policie and select the windows group policie. I checked the option only for the user settings. i uploaded the gpo to zcm and applied this policie to my devices.

If i look now on my devices the policie is assign and status is "applied and executed correctly" but the registry keys in HKCU are not set. What did i wrong?
Can someone please help me.
