Fixer Theme Gallery, Captions Not Displaying Correctly

Hi Support, I'm not sure how to fix this issue, as it seems that with the last update this change occured. There is a gallery on this page: http://kimlavinder.com/reiki/ at the very bottom. The gallery works fine but the captions are not displaying fully when you hover over the images. I'm attaching a screen shot to show you what I'm seeing.

I've granted support access for the site. Please let me know if you can assist. Thanks!
