Content - Events Booking Registration Form modal error

i'n getting the following error when I use the plugin button to insert a registration form in an article

Notice: Undefined index: filter_past_events in /administrator/components/com_eventbooking/view/events/tmpl/modal.php

For now, please go to Events Booking -> Configuration, set Debug Mode config option to No and it should prevent that notice from being shown

If you want it to be solved properly, get this file, unzip it, upload to administrator/components/com_eventbooking/view/events/tmpl and everything will be OK

Regards,
