Does not work translating from the language file

-- url of the page with the problem -- : ibaby.com.ua/cart
-- HikaShop version -- : 2.2.0 (Business)
-- Joomla version -- : 3.1.1
-- PHP version -- : 5.3.17

Does not work translating from the language file when order amount is less than the minimum amount (500 грн.) for the process of the order.
Displays the constant: "ORDER_TOTAL_TOO_LOW_FOR_SHIPPING_METHODS"

Hi,

Did you added a translation for the word "ORDER_TOTAL_TOO_LOW_FOR_SHIPPING_METHODS" through "Hikashop->System->Configuration->Language->'Your language file '" like : ?

I downloaded the language file from a website and there is this constant.
The problem started after the upgrade to HikaShop 2.2

Hi,
Can you replace your "YOUR_WEBSITE\administrator\components\com_hikashop\classes\shipping.php" file by the following file

Thank you. It works
