When Loop Playback is on, playing score jumps back to start from a place where there is no mark or indication to do so

The attached File plays OK (AAB) if Loop Playback is not selected.

But if it is selected, it plays A one first time, and the, instead of playing it again, it only plays the three first measures and the first quarter time of the fourth measure, to jump back to the beggining.

I've had similar issues in the past so I would guess it's a bug but I don't really know
any ideas?

thanks
