space underneath thumbnail?

Hi,
Love this widget!
The only issue I’m running into is a space underneath the post thumbnail which I display and the code for After every post.

The issue can be seen here: http://www.dailymom.com , on the far right sidebar at the very top called “Want To Escape?”

Under the General tab of the widget I have nothing in CSS class or any field except After posts:
<center>Discover more destinations >></center>

There are no stray <p>’s etc that I can find.

Is there an easy way I can close this gap somewhat?
Thank you!
