I recently added 3 different 'toner cartridges' to my watch list and when I select watch list, there is the option to display 'all categories' or a specific category. However, there are two 'Printers, Scanners & Supplies' categories: one with 2 items and the other with 1 item. Why aren't all 3 items in one category? Tried adding 2nd .jpg file showing the category with 1 item, but only one image is allowed to be posted.
