Address separator missing or wrong

In the list view, the venue address that is composed of street, city,… the separators are missing – everything is stitched together.
I was able to change the separator and insert the comma, but I don’t see how I can finish the address with a colon/point.
This is my modified version, but it is still very random: some addresses have commas now, but others have points. If I change the point to comma, I have a comma at the end of the address, where I would rather have nothing or a point.

if ( ! $event->venues->count() ) {
	return;
}

$separator            = esc_html_x( ',  ',  'Address separator', 'the-events-calendar' );
$venue                = $event->venues[0];
$append_after_address = array_filter( array_map( 'trim', [ $venue->state_province, $venue->state, $venue->province ] ) );
$address              = $venue->address . ( $venue->address && $append_after_address ? $separator : '.' );
?>
<address class="tribe-events-calendar-list__event-venue tribe-common-b2">
	<span class="tribe-events-calendar-list__event-venue-title tribe-common-b2--bold">
		<?php echo wp_kses_post( $venue->post_title ); ?>
	</span>
	<span class="tribe-events-calendar-list__event-venue-address">
		<?php 
		echo esc_html( $address ); 

		if ( ! empty( $venue->city ) ) : 
			echo esc_html( $venue->city . $separator ); 
		endif;

		if ( $append_after_address ) : 
			echo esc_html( reset( $append_after_address ) ); 
		endif; 
		?>
	</span>
</address>
