It sounds like your quiz settings might be set to display all questions on a single page instead of one per page. Try the following:
✔ Check QSM Settings – Go to Quiz Settings > Questions and ensure “One question per page” is enabled.
✔ Update & Clear Cache – If changes don’t reflect, clear your site cache and refresh.
✔ Theme Conflict – Sometimes, themes affect quiz display. Try switching to a default theme to check.
If the issue persists, consider checking QSM documentation or reaching out to their support. Hope this helps!
