Remove listing products under product detail page

Hi

I have been creating a store on business version and I have the following issue. I have a category Listing on the side bar and after a sub category is clicked it shows the related products on template body. When clicked on a individual product it goes to the product detail page which is all fine. Issue is that the same list of product are repeated under the product details under a heading "Additional Information" I tried everything thing I know to remove these products but I just cant figure out how. Please help, also I dont have live version yet due to still being under initial state of development.

Regards

Thank you for the reply.. I found out after hours of searching and experimenting It was due to
Config -> Display -> Default parameters for products -> "Content on product page" was set to same as category... I had to set it to related products and make sure that was not enabled under product details page. I dont know if was correct way but work for me.
