I'm using an iPad mini 2 with iOS 8. My language has always been set to Mexican Spanish and the iPad falls back to English by default, which is my native language. However, recently I installed a Japanese keyboard so I can enter specific words from anime to my friends easier, but I don't actually speak a word of it. Now my iPad is in Spanish with Japanese as the fallback so some buttons and apps are in Japanese even though I never changed any display language settings and just installed a keyboard. Going into my language preferences I get this. When I tap on either of them, they highlight but nothing happens. If I go "Agregar idioma"(add language) and select English, the iPad asks me "Are you sure you want your iPad to display in English?" Which I don't. So how do I change or remove the second language?
EDIT: I added English as a language and this added English to the bottom of the list so now I have the exact same issue with random words being in Japanese and no way to remove Japanese from the list.
