Eliminate second tuplet display

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.

Select the tuplet bracket you want to hide. Use Properties to hide the bracket and the number. Play around with those settings - you will get the hang of it. Its easier to try than to explain!

Thank you, Andre. Worked like a charm. And I also discovered that if I deleted the second whole note Dorico did not add a full rest (which is what I thought would happen).
