How to take Spanish off of my second language

I have had an issue with one of my cc apps. For some reason it added a Spanish â to my username and I could not sign in. I talked to the company and they told me I would have to use the â to sign in. So I went into settings and turned on the Spanish language. Well long story short it did not work so I went back and changed it to English. Well, now when I am texting it will just switch to Spanish from time to time. Can you tell me how to remove the Spanish from my languages? I see how to add languages but not how to remove them.
