I am working on a Bach cantata. I want to create several different parts for the continuo group: one for the cello/bass/bassoon (without figures) and one for the keyboard. According to the handbook, I should be able to remove the treble staff of the keyboard part and leave just the bass line. When I try to do that, it always deletes the bottom staff. This seems like a bug to me.
Additionally I would like the full score to only display the bottom staff (with figures), but it seems both staves are treated as one instrument in terms of visibility.
Ideally, I would do this all without having to duplicate things. I'm on OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 22.214.171.12492, revision: 58dd23d.
I've attached a score with a part extracted where it removed the wrong staff. I've also attached a PDF of what the full score and parts should look like.
