[Plugin: Events Manager] 5.1.3 EM_Location::Output bug

We think there is a bug with EM_Location::Output

EM_Location::output() mixes it up between $location_string and $format, but finally outputs $location_string. The filter below is called on $format, and changes are never output.

function filterLocationOutputCondition($replacement, $condition, $match, $EM_Location){
    if (is_object($EM_Location)) {

        switch ($condition) {

            // #_LATT{location_url}
            case 'has_Latt_location_url':
                if (is_array($EM_Location->location_attributes) && !empty($EM_Location->location_attributes['location_url']))
                    $replacement = preg_replace('/\{\/?has_Latt_location_url\}/', '', $match);
                else
                    $replacement = '';
                break;

        }
     }

    return $replacement;
}

add_filter('em_location_output_condition', 'filterLocationOutputCondition', 10, 4);
