Looking at your screenshot and the form, the form seems to be working properly.
The required field error notification is actually shown because your form has a required field that was empty when the submit button was pressed.
What you could do is to either:
1. make the field not required or
2. hide/disable the submit button until the email is entered
Do let us know of course if you need assistance with either.
