Why is the layout showing a single line staff, and using ledger lines to display notes? I am trying to get it to display as a 5-line staff. Please advise, thank you
Some folks have customized their Dorico implementation to allow/create staves with fewer than five lines to use with pitched instruments in particular situations.
I think that is in fact the problem, though I don’t know how you have managed to do it. If you remove all the existing components from the kit (with Remove All Instruments From Kit), then delete the (empty) kit, then create a new kit (with Combine Instruments Into Kit) then it all starts working.
