Excerpt (short decription) not working in Jet Events

Hi

I am trying to use the excerpt for to display on the event list page but I cant see where to add excerpt text in the event creation and using the “<!–more–>” tag in the description of the event doesn’t work either.

I can see see that the excerpt php is in the custom template and have set it to use the custom template in the backend. but no luck

<?php if ($jes_adata['jes_events_style'] == 'Standart') { ?>
			<?php _e('Short description:','jet-event-system') ?> <?php jes_bp_event_description_excerpt() ?>
		<?php } else { ?>
			<?php _e('Description:','jet-event-system') ?> <?php jes_bp_event_description() ?>
