Event Time Intervals

Hello,

I’ve used this snippet from the documentation to try to let events schedule within 5 minute intervals, however, it is still only allowing 15 minute intervals. Is there something that I did wrong here:

/**
 * Set event fields time interval.
 */
function gd_snippet_190307_event_time_increment( $interval ) {
	$interval = 5; // In minutes
	
	return $interval;
}
add_filter( ‘geodir_event_time_increment’, ‘gd_snippet_190307_event_time_increment’, 10, 1 );
