Before I done with mirror I have computer group workgroup on computer catalog but now is gone but if I trying to create the computer group workgroup is error pop-up with message group name already exist.
I don't know it is a bugs or not, after done with mirror update I also found that from AEA console can't create computer group.
The error pop-up is only Unable to create computer group "Uname"
I use AEA 7.0.118
