I have a song where two vocal parts are singing the same tuplet notes. When I crate the tuplet for the second voice on the same notes I end up with the tuplet (3) displayed twice/ Tje ste,s are up and down as they should be, but if I select the tuplet header, one set of stems are deleted.
Also, as included in the image I posted, if I place a the same whole note for both parts, two shole notes are displayed. If I drop one I’ll end up with a whole rest for that part.
By the way, these are barbershop voices, tenor/lead in treble clef and baritone/bass in the bass clef.
