Bad HTML/CSS for Badge Type Post

Using the badgeos plugin, I can produce a page with this short code:
[badgeos_achievements_list type=badges show_search=false]

From there, you’ll see various badges (ten in all).

Clicking on the name of an individual badge will bring you to a page that has the criteria, description, and the users who have the badge. Ex: Opinionated:
http://geohazards.community.uaf.edu/badges/opinionated/

Notice how the h1 tag for “Opinionated” is clipped?

This is a page that displays properly:
http://geohazards.community.uaf.edu/2014/02/17/plate-tectonics-3/

The only difference I can see in the page code is that the clipped page has an additional:
<div class="post-thumbnail"></div>
before the “entry-header” div.

We are using The WordPress theme “Twenty Fourteen”
