I am running a website in three languages (the default language is German). All texts are translated so far except "MwSt. 19%" (=VAT rate) at checkout page/tab in the French and English versions.
When I open the English (or French) version of the website, I still see "MwSt. 19%" (=VAT rate 19%) in German instead of "VAT rate 19%" in English.
Is there any way I could fix this?
In addition, at Shopping Cart page, if as a client I try to estimate shipping & taxes in let's say french, and then I decide to change the language website to English, then shipping costs will remain in French. Is this a bug from Opencart? Or how can I adjust this and make sure all these elements are in the same language?
In the attached picture, at checkout page/tab, 3 different languages show up.

Many thanks!
Kind regards,
