Hi Chris,
Welcome to Qsm Pro Support Forum.
As we are not experiencing this issue at our end, I suggest you to check for plugin conflict or theme conflict. To do this, disable all of the plugins 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.
Please let me know, whether this resolves the issue or not. Otherwise, we will need the admin credentials of your website and the quizz’s URLs to look into the issue.
Kind regards,
Kriti
