Problem when entering an override in the language section

-- HikaShop version -- : 5.1.1
-- Joomla version -- : 5.1.4
-- PHP version -- : 8.2
-- Browser(s) name and version -- : firefox

Hi,

I’m trying to make changes to the language file in configuration/ languages, but it’s not working. Am I doing something wrong or missing something? I’ve copied the line I wanted to change NEXT="Next" and entered what I wanted to say instead NEXT="Validate your address" in the override section on the right and saved it, but when I go onto the cart page no changes have been made. "Next" still appears instead of "Validate your address". See attached image.
