Note font was changed to drum's note and cannot revert back.

Procedure on how to replicate the bug:
1 Create a new score and write a simple melody on the Bass clef like so (attached below is a picture)
2 In the mixer, check "Drumset" and uncheck it. It will then not revert to it's original note.

Although the note is still a drum , the sound it makes (with the "Drumset" unchecked), is still the sound of the piano.

By the way, anyone know to fix this score attached?
