Registration Not Working

Hi Team,

I am not sure if it is happening with only me or not, I am using (using v2 beta), I tried to see all topics in support but nothing is matching with my problems, I am working on a website and trying to create a registration form for users so that before they post anything they must be registered.

Now when i go to form builder and try to add custom fields it allows me to create the custom fields.
The problem is that. when i go to registration page as a logged out user using a different web browser it does not give me options to register, please see the attachments. The predefined fields are not there like first name, last name, emails.

I think i found the issue but not sure how to correct that, please advise see the attachments.
