So are all the issues are where it transitions from B > A ?
If the transition started a bit earlier it should fix the issue rather than being directly on the bar.
In the drum txt file they seem to be set to Offset=-12
If you try that it might solve the transitions, you can try it and see what you get.

OFFSET=x

Often a drummer will hit a drum or cymbal slightly before a beat so that the actual peak of the sound occurs on the beat itself. The offset determines how many ticks (1 beat =120 ticks) before the downbeat a bar of drums will be taken from the style wave file, which is intended to compensate for any occurrence of this early playing on the drum track. It is important to note that if a bar is taken 10 ticks early from the style wave file, it is also placed 10 ticks early on the Band-in-a-Box® drum track, so there will be no shifting of the actual groove.
