Dublecate content and prestashop

[Timpet]

Hello users of prestashop and pundits.

I've read a lot about duplate content and sorting of pages and the next page features where you can browse or sort the contents. In prestashop displays a default description in the top of the category that comes with around on the page every time I turn the page in that category. Or if I choose to sort the products in a certain way will also dublecate content because the same products were also on the other side. Is there any way taken into account in prestashop and what can I possibly do to get the problem to life?
