I have used BiaB in the past, but haven't touched it in quite a while. Then my computer died. I got a new one and re-installed BiaB 2017 on the new machine. I began working to re-learn the software, and ran into an immediate problem.

I entered chords for a celtic classic, "Come To The Hills". It is in 3/4 time, so I selected an appropriate style and entered the chords for the first verse. When I play it, it counts 4 beats to the measure (not 3), and every third measure it counts a single beat and moves on to the next measure.

Is this how it is supposed to work? Am I missing something, here?

This link is to a video on YouTube showing the behavior. Any help would be appreciated.
