Deleting cues leaves extraneous rests everywhere

Probably I can’t reproduce this, but I just had a situation where, opening my score from 4 and editing in 5, which included cues across 4 instruments, to edit the score by changing measures (and modifying time signatures and adding bars, etc), in Galley view, then deleting the cues because they were getting too hard to read while editing, left a bunch of tiny rests everywhere in each player where the cues previously were; as if they were added voices, but they were not (and the extraneous rests were not selectable either, etc) . Expected behavior would be that deleting the cues would show the normal measure again.

Edit->Reset Appearance did not get rid of these.

When I switched to a different layout and back to the first layout, then these have disappeared. So the score looks OK now.
