"Duplicate" duplicates ancestor group, rather than the selected element/group

Dave shared this problem 4 years ago

I have seen earlier (two or three year old) posts about copying components from a group, and several of them are marked as "Answered" or have comments from Justinmind "Official Rep"s, but even with the latest Justinmind version (Justinmind Pro Edition Version 6.0.0), copying a child component of a group (or using "Duplicate") results in an entire ancestor group, sometimes 2 or 3 layers above the selected componment, being duplicated.
