I wrote a sticky post in the Tips and Tricks Forum about BIAB playing notes that are not in the chord you wrote, and some things that you can examine and experiment with to see if it makes a difference. The very first tip is Enter the Correct Key Signature. You can read the article here: https://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=694482#Post694482

There is a newer school of thought in jazz arranging that you just write everything in the key of C major and write all the needed accidentals. Personnally I can't stand that; using key signatures gives you additional information that assists in sight-reading and improvising. But if your chart modulates a lot within the range of just a few measures, there is something to be said for it. Just do not try entering that chart into BIAB; instead try to change the key signature as many times as needed to increase the chance of BIAB's accompaniment being pleasant sounding.

Awesome Matt! I am on it. So glad you directed me to that.

EDIT: This is gold!!!
