Help getting error on side of new event pages

Getting the following error but only when trying to create a new event. The error is on the side of the page where it normally has the options to put in the location, price, etc..

Warning: Illegal string offset 'level' in /home1/bcosc/public_html/wp-content/plugins/events-and-bookings/lib/plugins/eab-events-membership-integration.php on line 180

Thanks in advance
