Welcome Heelz.... The ads shown are sometimes based on a previous crawl of your content... I would give it a few days to see if it adjusts itself.

adsense has a bot all its own, check and see when was the last time the mediapartners google bot visited your site.

Google adsense always trails the content by atleast a week or so on my site.
