my apologies if this already has been posted.
The RM:s are out of position in the horn part, set to show to the right of clef and key sig.
RM:s set to left-aligned with systemic barline, horizontal offset 4 spaces to not interfere with the bar number. Bar number gone in the horn.
Seems like a bug to me. Can you reproduce this?
If I set barnumbers to not show in the layout settings, I get the same in both parts – but I would like to show the barnumbers.
