What should happen to a trivia duel when a question has two valid answers?

I handle marketing for LearnClash, where the questions are AI-generated. A lawyer who tried it recently flagged a question in his own field where he could make a case for three of the four answers.

In a duel, that could mean losing a point because the question wasn't specific enough. Even if it gets fixed later, you've already played that round.

How would you want a trivia app to handle that? Discard the question for both players, give credit for the other defensible answers, or something else?
