My guess would be it has something to do with the Count-In on the Wav file ..

Easy enough to highlight a couple measures of the Audio and Cut (using Close Gap) in RB to fix that .. but as far as root cause my guess is a difference in the Count-In settings between BiaB and RB or RB's interpretation of it ..

Hopefully others chime in with a better answer
