Thanks for posting your song. It doesn’t happen on the Transition Bridge for part 2 but does happen on the Transition Bridge for part 4. I’ve looked at the transitions in the BBMO and I’m not seeing anything out of place.
I tested it on the BB2 and it shows (the 7 measures in the measure counter) and plays the proper number of measures.
Not sure if this is the same issue: Struggling with multi-measure transitions but if it is, let’s see if Support, support@singularsound.com can clarify.
