Fix Email inputbox

Problem/Motivation

While going for the issues of the theme i found out that email box is having red star even though if the email is present in the input box

Steps to reproduce

Install them and add the email box and try to add the email within the box. Since I am taking reference of the issue from the demo site.

Proposed resolution

Red star should go away once the proper email id is present in the box. Fix the validation part properly.
