老问题：多part器件的annotate 如图

Cannot perform annotation of heterogeneous part 'U?A(Value 123)', part has not been uniquely grouped (using a common User Property with differing Values) or the device designation has not been chosen
Done updating part references

应该实现的编号是U1A,U1B,U1C,以及U2A,U2B,U2C，但是编了上面一排后下面一排就无法再编了，出了这个ERROR。请问应该怎么更正这个BUG?

路过。

樓主可以先試試delete掉所有part reference
