I'm not sure if this is related, but recently when an instrument played unexpectedly, I suggested:
Is there any chance that you have exported your BiaB song as an Audio File (Wav, mp3?). If so, the audio file with the same will play along with the BiaB SGU file. Check the folder that has the SGU file to see if there is an file with the same name.

I hope this assists in some way to help resolve.
