right alignment on exhibit index page?

Why is the first exhibit in my exhibits index aligning to the right rather than to the left like all the other ones?

It would be helpful if you included a link to the exhibits page so that we can see what else might be happening.

Here's the page:

It is possible that you may not have the most recent version of the Thanks, Roy theme, or that you've made some changes to the theme's pagination class in the CSS that is cause that first exhibit title to be bumped.
