Can you give little more detail - what sort of question came up and what were the choices? A multiple choice, a translation, pictures...?
it was english at the top "A story" and the build a sentence boxes at the bottom. One was "stori" the other was "Stori". usually the capital on one gives it away anyway, but yeh this was not a thing here.
Sounds like a possible glitch in the app or your device. You could try getting the latest versions of the app and your device's own system and see if that helps. The course team can only maintain and update the course database. Some of those updates seem to become available very quickly, others can take a while.
