Wordpress plugin quick fix

Hello freelancers, I need somebody to make a simple quick fix for the plugin : [login to view URL] Everything is working fine, except the featured items, when I go to advanced search and select categories I want to be listed, the plugin does not list all featured items (and there are multiple featured items) it lists some of them. If I select only 1 category, it lists the items correctly. Bid if you can do it, thanks.
