When using labels, searching [cftsearch] does not work

I found out that if using labels, searching [cftsearch] does not work.
I changed the source code of the plugin (custom-field-template.php) at line 3688 and it is working now:

Old code:

if ( !empty($val['label']) && !empty($options['custom_field_template_replace_keys_by_labels']) )
	$key = stripcslashes($val['label']);
$output .= '<dl>' ."\n";
if ( $val['hideKey'] != true) :
	$output .= '<dt><label>' . $key . '</label></dt>' ."\n";
endif;

Code after my change:

/* if ( !empty($val['label']) && !empty($options['custom_field_template_replace_keys_by_labels']) )
	 $key = stripcslashes($val['label']); */
$output .= '<dl>' ."\n";
if ( $val['hideKey'] != true) :
	// $output .= '<dt><label>' . $key . '</label></dt>' ."\n";
	if ( !empty($val['label']) && !empty($options['custom_field_template_replace_keys_by_labels']) ) $output .= '<dt><label>' . $val['label'] . '</label></dt>' ."\n";
	else $output .= '<dt><label>' . $key . '</label></dt>' ."\n";
endif;
