Selection Group Errors from inserted geometries

I build a big system in parts and then add them together by inserting geometries into a master assembly. It is also easier to create selection groups this way since you don’t have so many facets to work around. However these groups don’t get imported correctly. The imported selection groups are shown in the list but when you try to use them you get this kind of error…

Other times…I think…I noticed it selecting the wrong facets. Using MAC ARM 2.9.18 beta, but have noticed it in many previous versions too.
