The Product is missing from the email template

When people are registering it used to tell me what they were registering for. I accidentally click on delete filed and the hit undo. Now when people register it send me an email saying they registered but it doesn't tell me what they registered for. Here is a before and after shot of the email.

Would you mind letting us know the form URL so that we can check the payment fields in your email settings? I have noticed there are no Forms in your account.

Looking forward to your response.

Thanks.
