well, I kinda was in the opposite situation. Everything was in French except my music store which was in English (and I wanted French, cause that's where I'm from even though I left the country). I sorted things out by switching the store location: go to the bottom of the store's main page, you should have some sort of tab that says "My Store". Just switch to UK, and you're set.
Hope that's what you're looking for 🙂
