There's a language setting in the game, but also a language setting in the EA App. I wonder if you ended up purchasing a localized version of the game as described in this EA help article Change the language settings in the EA app. From that page:
Some games also have different versions that are specific to certain languages. For example, FIFA has an edition that includes English, Japanese, and Korean. A “Rest of World” edition is also available, and features a different set of languages.
You should probably contact them directly through that page for help (I don't think that this is a game bug that they'll be able to help with on this forum).
