Removing mysterious voice 1 rests on bar 2
I am writing a compressed SATB score, using voices 1-4 to separate the notes on the bars. For some reason rests belonging to voice 1 (Soprano) has mysteriously appeared on the men's bar, as shown in the image. Probably due to a mistake I did early on, when I typed in the tenor as voice 2 (alto), which I later corrected by selecting the notes and clicking the voice 3 button.
Apparently I cannot delete these rests, because "voice 1 rests cannot be deleted". There were voice 2 rests there as well, which I could delete, but these ones don't want to be deleted.
I even went so far as to try and copy/paste the notes to a new sheet, but lo and behold the rests came along and will not be denied. I cannot select just one voice and copy that, if I try to select more than one note, everything is selected. The "mark all similar" option does not allow for copying, apparently.
What can I do to get rid of them, short of deleting the men's notes and typing them in again?
