I'm not quite sure how you got to this but I have an idea that might help:
1. Go to Edit Quiz
2. Head to Answers
3. Change the drop-down next to Columns so that it says delete
4. Start with deleting one and only delete more if needed
If this doesn't at least do something towards a fix then, I know this sucks and takes a long time, you might have to restart the whole quiz. You can test your quizzes before you submit them and edit out any kinks.
Goodluck, I hope you find something that works. :)
thank you so much for this explanation, but I got it : actually I added colums to add answers, but only the first column can contain answers, and it goes to 500 answers maximum. So in result, i just can't add more words, so i think i'll do a second quizz with the rest of the lyrics.
