There is a setting in Engraving Options > Harp pedaling, where you can select if you want to allow partial pedal changes in a single line or to always show right pedals above left pedals. I have selected this last option, but when a partial pedal change of C# and D natural is added, the show one above the other (see attachment). But both are left pedals; why don’t they show on a single line?
I can reproduce it. It is undeniably a bug. But we’ll see what the team says
Thanks for the report, this will be fixed for the next update.
Thanks to you for the great work!
