registration_errors filter problem

I have a function set to list errors in my user registration if the registrant doesn’t include some custom fields. My understanding is that if the registration_errors filter returns an error then no registration will occur. This is precisely what happens with NUA deactivated, so I’ve isolated this to NUA.

The code that I’m using is:

function mmy_func($errors, $sanitized_user_login, $user_email){
    $errors->add('mmfail','Fail Message');
    return $errors;
}
add_filter( 'registration_errors', 'mmy_func', 10, 3 );

I tried to change the priority to 9 as well. The problem remained.

Please let me know if there is any other info I can provide.

Thanks in advance.
