Slurs and dynamics appear in other staff
I have one staff for oboe in my main score, but separate parts for voice 1 and voice 2. When I insert slurs, dynamics, and other markings for voice 1 (oboe 1), the markings appear in oboe 2 with no notes attached. This severely messes up the oboe 2 part as where they normally rest, it is empty measures with slurs and dynamics. Is there a way to designate a marking for only voice 1?
