Question for Drag and drop, Help ~~~

Hey,

Here is the question,

I am using drag and drop to create a test. I set the attempts as 2 to allow the user can try again in this test. However, it does not work. When the user pick the wrong answer, it directly went to "incorrect" page.

BTW, The try again works quite well with other quizzes in the same project.

Is there anyone have the same issue before? How can I solve it ? Thanks!!!
