If I add a question to an existing quiz and click on finish I go to the page with the answers. The correct answers for previous questions are not displayed (checked) as they are in the backend.

If I add the answer to the one new question that I added and click on submit I am told all of the questions aren't answered. So each time I have to re-enter the correct answer for every question even though I have allready entered them.

The correct answers are being saved since I can see them in the backend it's just an issue of having to re-enter answers multiple times.
