Using drupal render for Simplenews checkbox disables username and password fields.

Hello.

I have a user-register.tpl.php file in which I have:

along side several other renders, and when this specific one is active, the following renders: name, mail and password, do not output, which makes my user register page useless.

Anyone knows why and if there is someway I can avoid this? I have installed (but disabled) logintobbogan, since I thought these two modules didn't get along, but now I find this behaviour being Simplenews' only.

Thanks in advance.
