Claim Listings

Do you have more than one admin? This is the code that triggers the claim listing box:
if(isset($GLOBALS['claim_email']) && $GLOBALS['claim_email'] !="" && $post->post_author == 1 && get_option("display_claim_listing") =="yes" ){

That means that if the claim email is present and post author is admin (user with id=1) and you have the option to show claim listing set to yes it will show the claim listing.

If it does not show on your site, one of the conditions have not been met.
