Annotation Fails for a heterogeneous part in a special sheet

Hi,

I have created a heterogeneous part and I am using two of them in some of sheets in a design. Although I have used a uniqe part in two sheet, one of them fails in Annotation. I see below error message:

ERROR(ORCAP-1376): Cannot perform annotation of heterogeneous part 'U?C(Value AD9914) at location (2.80, 1.00) on page 07- DDS2 Power & CAPs', part has not been uniquely grouped (using a common User Property with differing Values) or the device designation has not been chosen

Thanks,

Hossein
