Ad-sharing displaying after every post

Hello.

Been using ad-sharing for a while with google ads and it's been working well. I just switched on one of my sites to tradedoubler to see if it would generate better revenue. After inserting the tradedoubler ad-code the ads are displayed after every post instead of after 3 posts as I have set.

Anything I can do about this?

Example: erikah.sportbloggar.nu

Thanks.
