Endless loop in category

The category: "Shopping: Antiques and Collectibles, radios" states that the category is for sites selling parts and radio related stuff, but if the site also sells radios, it should be listed in the following category instead:

Shopping: Antiques and Collectibles, radios

That's the same category. What the heck?:icon_ques

Blacksmith

Each category descriptions shows the description of the category itself (in this case there isn't any) and the description of all direct subcategories (in this case "Parts and Service Data")

If you look at http://dmoz.org/Shopping/Antiques_and_Collectibles/Radios/desc.html again, you might notice that the text you mention is in the section for the subcategory "Parts and Service Data".
