What happened to 'edit this submission' and 'view all your submissions' easily?

I worked on the email response for the form below.

I was getting the 'edit this submission' on my emails. 

Now they are gone.  I don't know why.

How can I get that back?

You might have deleted the row/text in the email notification accidentally. However, you may add the following text to the email notification so that it should be displayed with link in the email received.

You can {edit_submission} and {all_submissions} easily.

Thanks!
