Problem with wordpress

Hey, i am running a piwik for my wordpress blog.
It was a static page before few days and now is only a wordpress. I have the wp-piwik plugin and everything looks fine! But the only problem is it duplicate the first page of every visitor and track it for 1 sec!

Ex: I visit and after 10 sec i close the page! The piwik make 1 entry for that visit like a i have visit 2 times the same page! And always the first visit is for 1 sec!
