Marching snare notation issue

So for a few weeks now, not triggered by an update or anything, the marching Snare Drum has been inputting all notes two lines below the actual singular line in the percussion clef. How do I fix this? I already tried "Edit Drumset" and that dialogue says that the notes are being placed where they are supposed to be.

edit: I'm on version 2.1, just updated from 2.0.3 to try and fix the problem, didn't change anything.
