Ok this happens due to WP rich text visual editor misplacing div elements when auto formatting the code entered the content panel. This is specially true when the HTML is mixed with WP shortcodes.
Pls send me across a temp login to your page and I will take care of this issue for you – will need to insert the original HTML code and then insert line breaks around the div start and closures to help the visual editor do a better job of this. Thanks!
