What could be wrong with the Remove Email Verification Plugin

I tried testing my registration page with a new signup but what I get was that thee details of the registration that is the Login information and the password are being displayed before the page could even output the header. Which means the header comes immediately below that message. And this distorts the page making it look really unprofessional.

What do I need to do to get rid of this ?
Also my page is still sending that activation link to the user email, how could I stop this also?
