This is an issue that I have seen for some time but has yet to be fixed. When I go to sort my wishlist by edition the list gets sorted but it is not by edition. Can this issue be fixed?
Would you be able to provide some additional details? I just visited your inventory and sorted it by edition with no apparent issues.
I do know that there are issues with cards in inventory that appear in multiple sets (e.g., Divination). It will show up in the sort order with the other cards in the current set (that portion being displayed in the sort order), but it will also show all other versions of the same card in that set of results, too. That's broken.
