Drumset Notation in Wrong Place

Hello-- I'm working on a song with the drumset in it, and for some reason, the bar with the different types of percussion notes (the menu which usually appears at the bottom during notation) is in a weird little square at the top left corner of Musescore. It is so small I can only see one note option at a time and is blocking the "Format" drop-down while it is open. I have tried clicking and dragging the box back to the bottom of Musescore but it does not work. Does anyone know how I can move the box to its original place?
