I'm not sure I understand the issue. Are you saying you aren't seeing any email address, or you are seeing the wrong email address?
The address you enter on the "Edit Student Welcome Email" in the People section should be displayed, both on the email and on the confirmation page people see after completing their registration.
I checked your event, and it looks OK to me. If you can provide more information about what is wrong, we'll do our best to help out.
