Problem with double Images in Gallery

Hi Guys,
I am having a problem with the gallerypage. It shows all Images double in different formats.
When I have 10 pictures, the page displays 1 to 10 in thumbnail format, and underneath that it displays 10 to 1 in a bigger format.

I didn't post the images in the article, but only made a gallery.
I deactivated all my plugins, but the problem didn't dissapear.

Am I missing something here?
All help is welcome.
Thanx,
Sieb
