Heck, Microsoft got it wrong — Swedish versions of Windows used to have a folder called "Vanliga filer" (Ordinary files). This was, of course, the "Common files" folder, but the translator, probably having no context, picked the wrong meaning of "common", and chose a Swedish word which does not have the "shared" meaning.
In El Salvador (our TLD is "sv") we sometimes get apps or websites in Swedish because "sv" is used as a language abbreviation for Svenska/Swedish. Spotify was like that for months when it launched here.
When Windows 10 just came out, many of apps in start menu had a label next to them, which in Russian version said "Создать" (~Create). It took me some time to figure out that it's a poor translation of "New" (~Recently added). Proper Russian translation would be "Новое".
