@pete31, @BLUEFROG @cgrunenberg Thank both!
@pete31 Your detailed guidance was instrumental. I missed:
- "
Exclude Groups from Tagging
andInherit Tags of Groups
." - " *
Preferences > General > Unify tags
" did the trick too!
Also, I found unchecking Preferences > General > Unify databases to be quite helpful.
Again thank you all for helping move my key database, it’s groups, tags and nested relationships forward in time.
