Why does Rosetta Stone teach the British Pound currency as to be translated into other European languages is not Pounds but other words like French Livre and German Pfund? Is this really how it works in other languages regarding the UK's currency?

Started going beyond Greek and sampling some lessons in other languages and I notice when the UK's currency Pounds is involved in the question, the translated word in other European languages is different and not pound itself. For example the French lessons asks how much a sandwich costs in Pounds and the answer selection is X number of Livres, the Italian counterpart of the same lesson lists X Stirling. In the German lessons the answer selections is Pfunds and the Dutch and Swedish similar words like Ponds. Portuguese and Latin American Spanish use words similar to the Italian one and the European Spain course uses Libbras or something similar tot he French one.

I ask why? All other currencies used for exercises in the app like American dollars, Euros, and Yen are all shown pronounced and spelled exactly in their original languages esp if you're using a course with the Latin script of most of the European languages featured in the software. Is it really actually like this when talking in other languages about foreign currencies? So if I go to say an currency exchange store at an airport in Italy, I should ask about buying Stirlings if I plan to fly to London in a few days after staying in Italy? or if I'm from London in a trip and will fly to Brazil later, when I go to an exchange spot in Rio I should tell them I'm changing Libras in a written note and not use the original English word that is Pound?
