In both includes/modules/product_listing.php and includes/modules/all_business/product_listing.php the code is as follows on line 191 but yet I can still not get the image to show for items offering free shipping

Code:
$lc_text .= '<br />' . (zen_get_show_product_switch($listing->fields['products_id'], 'ALWAYS_FREE_SHIPPING_IMAGE_SWITCH') ? (zen_get_product_is_always_free_shipping($listing->fields['products_id']) ? TEXT_PRODUCT_FREE_SHIPPING_ICON . '<br />' : '') : '');
Any ideas?
