The quiz looks different on the front end compared the preview. According to the plugin information it could a conflict with your theme.
I tried to read about it but is to complicated for me to understand. Is it any possibility you can help me with the coding?

I logged in to your website. It seems like you are having plugin/theme conflict on your website. To check for plugin conflict or theme conflict, disable all of the plugins all at once and enable one by one by checking which one is causing the conflict. If this does not resolve the issue, change the website’s theme to another theme and check whether the issue is resolved or not.
