Themer archive page does not show the right posts

Hi I can not get a Themer archive page to show the right posts. For instance in this page I have some posts modules set to show “all related categories except” option.
But it is not showing the posts with the category “kunskap” Instead it is showing /artiklar/ categories for the first posts. The first posts does not even have /kunskap/ category assigned to them.
However this page shows the right posts.
Some of the posts have more than one category assigned to them. But since the archive page should first look for posts with a “kunskap” category. Or do I get this all wrong?
Maybe I have to create a Themer page for every category (witch would be a pain)
