Why does this "Request More Information" page has a locked Date of Birth?

Summary:

when I hover on the Date of Birth field on the request more information page, I can see a field tip pop up.

This message is unclear and wouldn't make sense to the candidate.

If there's going to be a field tip there, it should explain why the field is not editable.

Can someone please help me with this?
