Welcome to the forum, Frank.

I do recall having this problem years ago, but just now I tried various key signatures and my BIAB 2020 accepted Gb and F# entries, preserving each in my song, no matter what the key signature.

1. Could you tell us, what version of BIAB are you using, and is it for Windows or Mac?
2. Are you using any upper extensions on your chords?
3. Just making sure, we are talking about typing the chord into the chordsheet, and not some other form of data entry, like the Chord Builder?
4. Could you give us the exact steps you are taking, so we can duplicate the test?

Another possibility: when BIAB is not doing what you know it should, do Options, Return to Factory Settings and test again. You will first have a chance to save your settings in case you have made many adjustments to the defaults.
