Can someone help me get to grips with why BIAB won't play the right chord extensions sometimes?

I've just spent a while going through a bunch of great jazz bossa styles and none of them would play the a #5 extension on a dominant 7 that I wanted. I've had to make do with a motown style.

I can't make sense of the chord settings window, does that control some of this stuff?

Could someone point me in the right direction please?

Thanks in advance
