Characteristics displaying as products?

-- HikaShop version -- : 2.6.1
-- Joomla version -- : 3.4.8
-- PHP version -- : 5.4.45

I noticed that if I created a category type menu item and used Product Category as the category that there are items on that page. Going to the backend and filtering the products to show direct sub items from "Product Category" that there were 19 "Products" clicking on the "products" in this list opens a page to a product, but not the one listed in the list. For example, In the list for "product category - Direct Sb Elements" the first item is "30ft 4x4 gauge steel pole with 2 3/8" tenon top" . Now, this is a characteristic option - not a product. If I click on this it opens "1 Light Adjustable Option" that is a product in the "LED Parking Lot Pole Kits". By far the craziest thing I have seen in the 4 years we have building with Hika.
Is there something I have done wrong or that has changed in Hika that should cause this?

After trying what was suggested I had no luck. However, I did solve this but found that it was due to an incorrect import by the client's staff.
But just to clarify, should I avoid an alias that starts with a numbers in the future?
