Help with Groove Agent bug creating snare sound from nothing

In this particular song I’m working on, whenever I arm the Groove Agent track and play, I hear a snare, despite there not being any midi notes on the track itself. It does this if I change the kit too. I’ve tried adding a brand new instrument Groove Agent track but it still does it. I’ve muted every track as well. Why might this be happening and what can I do to fix it?
