Error in registration buttons inside event

Hello,

Somehow the registration buttons are not showing in an event anymore. They do show in the overview via de menu link "upcoming events - timeline overview" 
I get the following error:

Warning: Undefined property: stdClass::$is_multiple_date in domains/mydomain.com/public_html/components/com_eventbooking/themes/default/common/buttons.php on line 37

Warning: Undefined property: stdClass::$can_register in /home/domains/mydomain.com/public_html/components/com_eventbooking/themes/default/common/buttons.php on line 39

Warning: Undefined property: stdClass::$waiting_list in /home/domains/mydomain.com/public_html/components/com_eventbooking/themes/default/common/buttons.php on line 43

Software used: Joomla 3.10.12 // Events Booking 4.6.1
Can you help me with a solution? I have seen the error on other websites (e.g this one ) on the internet as well.
