Sentence is instantly reviewed / appears twice in a row

Occasionally while doing the extra practice the arabic from english course, a sentence answered will give one a second chance to answer, the display stuck, still showing both the correct and incorrect answer. If correct, the score awarded will instantly be worth as many points as if it was in review. The rounds can continue as normal, and it has not happened twice a round.
