@Sylmos I'm glad it's fixed. The EA App doesn't handle language-related questions well right now. In addition to lacking the option to switch languages, the App sometimes installs in the language of the App itself instead of the player's chosen language, which can be even more of a problem when the App doesn't even support certain languages that Sims 4 does.
As for the user folder, all but four of the game's languages place user files in "The Sims 4," even if the folder might logically be called something else in that language. (Exceptions are Spanish, French, German, and Dutch.) Some subfolders have the same names too, while other folder names are localized, and all these subfolders end up in the same Sims 4 folder, as you can see in your screenshot.
