Re: TS4 Digital Deluxe languages.

I haven't played The Sims 4 in a while but was really excited for the new Expansion Pack. After purchasing it via a retailer I discovered Origin no longer works so had to switch to the EA app. I couldn't play The Sims at all, I got a notification stating I wasn't qualified to run The Sims in the current language (f089e35b:tonsofzeros). I repaired the game and it launched, but in English, eventhough I always played in Dutch with Origin. I learned the only way to change the language is to reinstall the game, but when I click the download button and get to choose the language preference, I can only chose English in the dropdown menu. 

As stated, I previously played The Sims in Dutch. I checked the new Expansion Pack and it comes with all languages as well. What is going wrong here?
