Thumbnail location is messed up.

Hi, I really impressed this theme. It is awesome to build nice web site.
I have run into an issue recently. The alignment of thumbnails in category archives is messed up.
The thumbnails must be aligned left and right in rotation. But the thumbnail on the top of the page is not correct location.

Here is the link of the page.
