First set of posts repeating

Hi, I just installed this plugin today, and have it all setup and almost working perfectly. The problem I’m running into is the first time you click the ‘Load More’ button it relaods the first posts that are already on the page. Every time after that it loads the next batch of posts.

You can see this at one-quest.com

I’ve got the code added directly to the loop-posts.php file with the following code

<?php
echo do_shortcode('[ajax_load_more [ajax_load_more post_type="post" pause="true" scroll="false" button_label="Load More Posts. . ." posts_per_page="10" container_type="div" ]');
?>

Any help would be much appreciated.
