Hi hitler2napolian,
I went through your listings, and I dont think there is any duplicacy in the same.
A duplicate listing is one when you list the same item twice. Your listings appearing in your shop are not duplicate listings.
On your Turbo Lister question, the category will depend on the products that you are listing. Since you are listing mostly in Stamps and Coins category, the following link will give you the list of all sub-categories that are present in the category.

If any of these categories are missing in your Turbo Lister then update your Turbo Lister from the following link - http://pages.ebay.in/seller_tools/index.html#turbo_lister
Do let me know in case your question is unanswered.
Regards,
Sapana
