‘Pages’ muliplies (sometimes)

Hi

After upgrading to 1.5 I decided to use the pages instead of normal post for some parts of my site as link, archive and about etc. The strange thing is when I did move the content to the pages it turns up double on my pages, there is some other things too that doubles as my goodle ads and the comments.

Here is an example

The even stranger thing is another page made the same do not ‘double’ it self, see

First I thought that I made some errors in my index.php file but then I changed to the default theme and there is the same problem.

Thanks
