Automatic translation off

Please, I’ve been using formative for a while teaching English as a Second Language, but lately my students are telling me that all the questions and answers appear in Spanish as we are native Spanish language speakers. This makes formative completely useless for my class and I imagine for many other Second Language teaches like me. So far, I’ve promoted formative with all my colleagues and friends and I’m sad to see that almost all features here aren’t an option because translation gives away the answers… Please help us out, let us have a switch or something where we can choose to turn translations off.
Thank you!
