V key makes everything invisible MuseScore 3
The title says it all. V is not assigned as a shortcut by itself, but typing the V key (upper or lower case) makes whatever has been selected invisible, even if it's text/lyrics. The letter v isn't typed either. I can't find any setting that might address this. The shortcut to actually make things invisible is something else. I've even tried exporting the settings and restoring defaults, but no go.
This didn't happen when I installed MuseScore 4 and imported the shortcuts, but there are so many functionality limitations with 4, I want to go back to 3. It's getting ridiculous. I spend more time just trying to find functions, half of which seems to have been removed...
What else could be the cause of the involuntary invisibility key?
