The Main score's Staff Text gets unintentionally duplicated in Parts (under certain circumstances)
Regarding scores with linked tablature and subsequently generated Parts, I often find that for each Staff Text object added to the main score two Staff Text objects appear in the Part. As far as I can telll, it doesn't matter if these objects are pasted or newly created.
The same can occur with Chord symbols. Update 2022-08-06: Turns out there's a long list of objects that appear "doubled" in Parts when added to the score after generating players Parts.
Note: I've only tested with linked tablature.
I see these issues as significant because it appears that the only "remedy" is the deletion of Parts in which they manifest—and that's at the cost of time carefully spent grooming the Part's layout. So it can be a sizable loss.
Best I can tell the issue exhibits only after closing and reopening the score! Due to this close/open trigger exact steps to replicate had proved initially elusive, but I have listed steps in the original forum post.
Update 2022-08-07: I've listed a shorter number of replication steps below.
It seems the bug trigger is a conflagration of Parts, Linked Tablature and a Close/Reopen cycle. After that point various objects added (pasted into?) to the main score display as pairs in the Parts.
