OK, here's what I think happened (ala Monk)...I copied a listing from a sold item as a base for a new item. When I subsequently edited the listing again, it renewed the original sold listing, and so I have two.
Also...I searched my sold items for the original valentine bobbies the new listing was copied from and it shows as being sold, yet not sold out. The listing is not in my shop, inactive or expired lists. I have only been charged for my original listing (the top one), and not the other one.
