Are you sure these items are not split between categories?

Could you try removing these items from the shop, and then adding them back in?

If the error persists after that, please let me know the exact method you used to add them into your shop (quickstock, from vault, or from inventory) and what results you get if you search for just the item name on the Edit Items page.

So it's resolved? :P Just making sure I understand your post correctly.

Awesome! Locking this up now. :)
