[Plugin: Custom Field Template] Search results replace WP menu on website??

Im using custom field template plugin & have created a search of my custom fields. this seems to work fine, but on the results page, all the result’s permalinks are replacing my theme’s menu & i have no idea why!

To see what I mean, please go http://www.gchr.com.au/gchr-specials/test-search/ and only enter “Surfers Paradise” in location and hit “search”

Im using the WP menu on my site <?php wp_nav_menu( array('menu' => 'main menu' )); ?>

Does anyone have and idea how this is happening and how to fix it? The same thing happened with the “WP Custom Field Search” plugin results.

I should also add that a normal site search does not cause this problem
