Click Quiz Error? (Fixed)

I was making a click-quiz, using the 'many to one' form, and when I previewed the quiz, one of the answers was duplicated, with one of them at the front, out of alphabetical order.

I checked, and they were spelt the exact same, and I have no idea what happened.

Could someone check the quiz for me, or, if you're familiar with similar issues, instruct me on what to do?

Thanks!
