Uhh... that's kind of how these algorithms work. I presume you interact (i.e. don't scroll past) with a lot of the English posts. It's going to index on that and show you more English content. When I'm abroad, I might see a few posts in their native language but the algorithm will revert to showing English posts about the city/country once it realizes I'm not really jiving with Portuguese posts, for example.
