Ha. Yes, I've had this happen from imported files.

BIAB used to have a Panic button to silence MIDI. To my knowledge, that is no longer there. But just exit BIAB and it will stop.

Once back in the song, go into either Editable Notation Mode or Staff Roll Notation Mode (Piano roll), find the offending note, and change its length.
