Missing required data in email notification

In my form, I have a required field for date of birth and when the email comes in, that data is not provided in the email. I would like to know why this is occurring and how to fix the issue. When I login to jotform the data is there but it is blank in the email. 

I checked your last couple notification emails and it looks like you have resolved the issue, possibly by deleting and then recreating the notification email.

If this is still not as it should be on your end, let us know and we will take another look.
