Event details are not displayed

There is a bug about in line 277 of code in event-organiser-event-functions.php

if ( ! isset ( $occurrences[$occurrence_id] ) ) {

		$result = $wpdb->get_row($wpdb->prepare(
			"SELECT event_id, StartDate,StartTime,EndDate,FinishTime FROM {$wpdb->eo_events}
			WHERE {$wpdb->eo_events}.post_id=%d AND {$wpdb->eo_events}.event_id=%d ORDER BY StartDate ASC",
			$event_id,
			$occurrence_id
		));

// LINE 277
// incorrect
if ( ! isset ( $occurrences[$occurrence_id] ) ) {

// correct
if ( ! isset ( $occurrences[$occurrence_id] ) || false === $occurrences[$occurrence_id] ) {

// LINE 281
// incorrect
			WHERE {$wpdb->eo_events}.post_id=%d AND {$wpdb->eo_events}.event_id=%d ORDER BY StartDate ASC",

// correct
			WHERE {$wpdb->eo_events}.post_id=%d AND {$wpdb->eo_events}.event_occurrence=%d ORDER BY StartDate ASC",
