Using Contact Form 7 and Event+ together causes errors pointing to Event+ when saving contact form

So when I save a form in Contact Form 7 by Takayuki Miyoshi. I end up with two errors that point to the Events+ plugin.

Notice: Trying to get property of non-object in /home3/jonaswa/public_html/test.jowebdesigner.com/projects/twps/v4/wp-content/plugins/events-and-bookings/events-and-bookings.php on line 375

Warning: Cannot modify header information - headers already sent by (output started at /home3/jonaswa/public_html/test.jowebdesigner.com/projects/twps/v4/wp-content/plugins/events-and-bookings/events-and-bookings.php:375) in /home3/jonaswa/public_html/test.jowebdesigner.com/projects/twps/v4/wp-includes/pluggable.php on line 1179

How can we/I fix this? I would like to have this fixed before handing this off to the client at the end of this project.

Thank you
