Attendees List not showing anymore

This is a attendeeslist.php file.

<?php
/* @var $EM_Event EM_Event */
$people = array();
$EM_Bookings = $EM_Event->get_bookings();
if( count($EM_Bookings->bookings) > 0 ){
	?>
	<ul class="event-attendees">
	<?php
	foreach( $EM_Bookings as $EM_Booking){ /* @var $EM_Booking EM_Booking */
		if($EM_Booking->booking_status == 1 && !in_array($EM_Booking->get_person()->ID, $people) ){
			$people[] = $EM_Booking->get_person()->ID;
			echo '<li>'. $EM_Booking->get_person()->get_name() .'</li>';
		}elseif($EM_Booking->booking_status == 1 && $EM_Booking->is_no_user() ){
			echo '<li>'. $EM_Booking->get_person()->get_name() .'</li>';
		}
	}
	?>
	</ul>

Dear Events Manager team,

I got this message in the console. Maybe this will help.

just to narrow down the problem and help us debug the issue is it possible to try the following temporarily:

– deactivating all other plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the default theme to rule out any theme-specific problems

I already try these options.
Do you know a way to roll back to a previous version then update to version 5.9.5.1.
The second issue is when people click on “Send your booking” a paragraph “Booking successfull” appears in green, but people can book twice a same event. Because the option “Send your booking” did not change and close like before.
The option is set to 1 booking per person and was working fine for the whole last year.

I got the same issue than in another post that I found here.

PS’ If I buy the PRO version can you fix quickly this 2 troubles.
If yes, I buy the PRO version today.
Cheers,
Remi

you can try the latest EM Dev version 5.9.5.2
