My SIMS4 is English only

My game changes language to English automatically with each update. Even worse, if I want to use another language, I have to uninstall and reinstall the game to get other language options! Otherwise, the dropdown page in my setting will be in English only (see the attachment). 

I've asked the staff 3 times and got the reply that because my first download was in the UK, my game was English only after that. It's so annoying, especially as I didn't get any language options when I first downloaded it, only English. And it doesn't make sense that by default if I buy a game in the UK I can only use English.

Some of the things I've tried are: reinstalling EA, completely removing and reinstalling sims4, leaving UK and repeating the above. All of these ways only briefly change my language to some else until the next update. Once updated, my sims4 goes back to English again.

I want to get the experience that all players get: switching languages smoothly in the setting rather than reinstalling the game every time. It's wasting a lot of my time! 

PLEASE let me know if you run into the same problem and find a way around it. It would be really help!
