Well, after some drama in getting the battery replaced on the Windows notebook/tablet and dealing with Lenovo's/Window's reaction to that, I have tried to recreate this problem and can't.  The problem is definitely not anything to do with the characters used in the setlist name since I tested that.  Unfortunately, I don't have the original backup that exhibited the problem.  I'm left thinking that it was a result of either some odd glitch in that particular backup operation itself, or that it was a result of my doing multiple adds/deletes to the setlist as  I was also moving things around in it -- though that certainly didn't manifest on the Windows side, and testing that thoroughly would be very time-consuming.  I'm going to regard this as "not really a problem" and live with the single anomaly unless it happens again, which I think is unlikely given how much the backup/restore operation has been exercised at this point.
