Sorry for being absent from this thread. I was away and set my
subscription to nomail, and hadn't bothered to look at the archives.
My bad.

Anyway, In my case, on Jan 3, I set "Max Children = 2". It had been 5.
I so no more dups until one on Jan 19. I then set "Max Children = 1"
and have seen no further dups.

I expect that I would never see any dups of this kind when "Max
Children = 1", since dups apparently only occurred when two separate
children picked up the same entry.
