Email doesn't include full form

One of my forms doesn't include all the pages of the form in the email submissions. Sometimes we get the first page, sometimes we get everything but the last page. What could be the problem?

If you have selected to hide the empty fields in the notification, they will not be included in the email. 

Please check if this option is checked in the email notification. You may also try setting up a new notification and see if that works.

Please get back to us if the issue still persists. We will be happy to help.
