I made a mistake on parent's information in FERPA section in my common app

I was filling out the FERPA section in my common app and I put my mom as the assigned parent for Early Decision Agreement but I put the wrong email address. I try to go back and edit the information but there is no such option on the page and I couldn’t fix the email address. Now how can my parent sign the agreement? She wouldn’t receive it electronically with the wrong email address.
