Rehearsal marks above percussion

Hello - I have a percussion part in my score, and my rehearsal marks are not showing above it despite having selected both ‘pitched’ and ‘unpitched’ percussion in the layout options. Any ideas? The percussionist is setup as a ‘kit.’

Also is there a way to adjust the rehearsal mark font in just one layout, as opposed to globally across all layouts? That would provide me with a suitable workaround.

Does a bracket appear in the score for the percussion instrument? System items like rehearsal marks etc. will only appear above the first staff in a bracketed group.

Ah that’s it. Thank you!
