Error message when displaying directory listing

On my prostatecanceralliance.org I get the following error on the listing display page:
Warning: Invalid argument supplied for foreach() in /home/darrylmi/public_html/wp-content/plugins/directory/ui-front/general/display-custom-fields-values.php on line 45

You can view this on the sample I set up at:
