Even if you set 'Retry' and 'Show solution' to 'Disabled' they still show after you finish the quiz and you can still retry. This is a bit strange when you don't want to reveal the correct answers or the users to have unlimited tries.
1. Answers are not revealed when 'Show solution' is disabled.2. Not possible to retry when 'Retry' is disabled.3. Update https://h5p.org/comment/11619#comment-11619
