I use the Auction Title Sorts to ensure I do not duplicate any listings
There seems to be a glitch there today.
I was in MG Stamp Shop - Thematics - Animals and Birds
Used the Auction Title Low to High sort and got the following results in part of the sort
Romania 1977 Protected Animals
Romania 1989 Timisoara Nature
Romania 1977 Protected Animals Bison
Romania 1989 Timisoara Nature Philatelic
Romania 1996 Atlantic
Romania 1977 Protect Animals Coypu
As you can see the items are not in order
At one point one of the items appeared on page 1 and on page 2 (because they were in the wrong order) so I thought I had accidently duplicated a listing. While I was checking to see that the two items were duplicates the first item disappeared and reappeared in the correct place order and was not duplicated.
I very nearly deleted an item unnecessarily!
I have not had this problem before.
