Issue: Templates in 10.2.1 have no Metadata

[charon]

Hey Cognoisers,
we are currently experiencing issues switching from cognos 10.2.0 to 10.2.1 (FP 4 i believe).
Creating a new report in report studio or workspace advanced with a Template shows no metadata, no matter what package or data source we are choosing. The data source panel keeps empty and displays "no metadata available".
Creating a normal list or crosstab works properly. Opening existing reports based on these templates work properly as well. Anyone else has similar experiences?
Environment: Cognos 10.2.1, CQM DMR Package, Oracle 11g
