How do I reset the questions for subsequent attempts to pass test

Hello there,

Due to compliance issue I cannot share the project files with you. But if you could understand the issue and provide me the solution then it will help me a lot.

Here it is:

I have set of 22 questions in question bank. In 1st attempt everything is working fine.

Like: Selecting Option/Answer, and then if I click the submit button without selecting options/answers, the default message (Please complete the question before clicking the submit button) is also appearing and result page (unfortunately you didn’t pass the assessment click retry button to re-attempt the assessment)

Issue:

Here when I am re-attempting the assessment, its allowing me to go the next question (after clicking the submit button) without selecting an of the options/answers, and the default message is also not appearing (Please complete the question before clicking the submit button).

Regards,
Dipu
