Emails all say undefined in body

We started receiving emails from the form we created today that say Undefined instead of showing the forms content. I've cleared our cache and deleted our email notifications to add them fresh again and we are still having the issue. 

I have added my email address in your current notifier and tested your form and the email contains the correct data:

Did you embed the form to your website? If so, please let us know the link here so we can test/check it further.

Thanks
