I recently deleted one of my shops and while on the drop down menu it says that certain shop is gone (while my other two still remain) when I click on the "my shops" option there is nothing there. Furthermore when I tried to edit the prices of one of my shops it would not let me, and when I removed the items selecting "move to shop" did nothing and they ended up back in my inventory.
I am unsure what happened as my items in my gallery still exist but apparently not under the "my shops" details.
We recently switched to a new shop system. So if you haven't created a new shop you should. The drop down menu is the only way to get to your legacy shops and you cannot price anything in them anymore since they are wanting people to move to the new shops.
