Repeated "Listing" x 45 in source code

The listing archive page:
http://tamworthcountrylife.com.au/listings/

On line 436 of the source code repeats the word "Listing" about forty five times. It can be seen in the front end behind the main navigation menu.

This does not happen within categories and sub categories or any other page on the site.

I believe it to be a conflict with the mega menu extension of the theme but wish to modify the directory plugin to rectify it.

Please any help or advice on the matter would be appreciated. I seem to have had a lot of problems with this plugin... any rebuild planned?
