Not Working in Tabbed Boxes

When I trigger the expand in a tabbed box, all other text (outside the code) get pushed way down to the bottom of the page, below the tabbed box. This happens even when I just have one line of hidden content.

You can see what I mean here: http://docstorystudio.com/the-directors-journey-2/

Any help would be greatly appreciated! I love this plugin and really want to make it work on my site.
