Listing search widget displaying meta titles

Hi,

Just updated to 2.2 and noticed a bug.

The ‘house category’ field on the search widget is displaying meta titles in the drop down rather than the actual text values.

I am using the ‘Easy Property Listing – Filters’ mini-plugin to create custom values for this field:

 function epl_fl_property_category($array) {
	$array = array(
			'cave-full'		=>	'Cave house - fully reformed',
			'cave-part'		=>	'Cave house - part reformed',
			'cave-un'		=>	'Cave house - unreformed',
	);

Thanks.
