Adding subscribe checkbox to registration page ruins form order

When this module is activated and the option to add a subscribe checkbox to the registration page is checked, it redraws the registration page and puts the default form fields inside a fieldgroup. But any "user registration guidelines" (set at /admin/user/settings) that are supposed to appear before the registration form are moved to below the standard form.

i.e. Default order:

1. User registration guidelines
2. Default registration form
3. Submit button

After activating this module:

1. Default registration form (enclosed in fieldgroup)
2. User registration guidelines
3. Subscribe checkbox in fieldgroup
4. Submit button
