Not sure if this is specific for MV22, but I have a MV21 running on MV 3.31 that does not exhibit this behavior. Motion windows correctly reflect motion that can be seen in historical video feed.
If you haven't already, I would recommend submitting a ticket with support so they can help you determine if this is a bug. You can do so via dashboard under Help > Get Help menu. They will likely ask you for screenshots of the behavior to expedite the process.
