I'm new to musescore, so I'm not sure if this is a bug or just me not knowing the software. I noticed that my dynamics don't really work for the piano part in the piece I'm composing. All the piano staffs always stay at whatever volume I set the lowest staff to, even if I assign different dynamics to each staff. If the bottom staff is mp, the entire piano part is mp. If it's f, the entire piano part is f. How do I fix/change this?
