Shortcode permalink not working

WP Version: 4.9.6
Events List Version: 0.8.3

Problem: Shortcode [events-list] permalink wasn’t rendering correctly:
returning: {current_psot_url}/?event_id1={event_id}

Solution:

Modified (event-list/includes/sc_event-list.php Line 447

Changed From:
return esc_html(add_query_arg(‘event_id’.$a[‘sc_id_for_url’], $event_id, $this->get_url($a)));

Changed To:
return get_permalink($event_id);

Works perfect… may want to evaluate & push an update ??
