Can't group or ungroup playing techniques in percussion

Hi, grouping or ungrouping playing techniques in percussion don’t seem to work here.
Tried several scores, both created in 3.5 and in 4. Latest Dorico, Mac, Monteray.


Edit: hm, just created a new score with just bongos and here it works. Seem to be only with percussion kits it’s not working.

Edit 2: It works if I change to single-line instruments.

Thanks, I’ve made a note of this, but I don’t know when we’ll next be working in this area.

This has been reported some time ago. It doesn’t work in 5-line staffs, but if you have single line view, group them and then change back it works.

Thanks, can work around it changing to single-line and back for now.
