No address_middle_name on the invoice

-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : x.x.x
-- Joomla version -- : x.x
-- PHP version -- : x.x.x
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message

On the invoice there is no address_middle_name while there is at the email, at the orders there is and also at account information.

My address_template is this:

<?php
/**
* @package HikaShop for Joomla!
* @version 2.3.0
* @author hikashop.com
* @copyright (C) 2010-2014 HIKARI SOFTWARE. All rights reserved.
* @license GNU/GPLv3 www.gnu.org/licenses/gpl-3.0.html
*/
defined('_JEXEC') or die('Restricted access');
?>{address_company}
{address_title} {address_firstname} {address_middle_name} {address_lastname}
{address_street}
{address_post_code} {address_city} {address_state}
<?php echo JText::sprintf('TELEPHONE_IN_ADDRESS','{address_telephone}');?>


What is wrong?

That was it, thx.
