Problem with multiple question/answer

Hallo,

first many thanks for the Plguin.

But i have some trouble with multiple question/answer which i have define for the quiz.

If someone answer the question incorrect, contactform 7 generate a new question but the placeholder for the quiz field shows the old one. So the user has no chance to give the right answer.

Can you help me?

Many thanks in advance.
