Language has changed and I can't change it back

I've been watching Lego Ninjago on my account and have just finished the first season. I went to the first episode of season 2 and had noticed it changed to Swedish.

I tried going to the language setting on the episode and only had the option to use Swedish so I tried going to the language setting for my profile and it was already on English.

The preview is in English, info and menus and the entire first season was also English. Any ways to fix it?
