Permalinks problem

Hi guys.

I am having a mistake on my website..
in permalinks in my hyperlinks it shows
“catogory”/real category name/postname
it should just show
real category name/postname

It does only show that hyperlink when i click on a category..

When i show a post, it works fine as
real category name/postname

here are my links
http://www.rateclubgirls.com/category/sweden/gothenburg/ (wrong!!!)
http://www.rateclubgirls.com/sweden/gothenburg/ (Should look like)

a post http://www.rateclubgirls.com/sweden/gothenburg/hello-sweden/ (post hyperlink world fine)
