Certain Questions Not Appearing in Live Mode

I’m having an issue with over 13 questions not appearing in the “live” mode of my survey. On the admin side, all of my questions are set to be “required” and I do not have any logic jumps. I have hit Publish multiple times. My client took the survey and only half of the questions were answered. I thought it was strange that the system let the survey be submitted without answering 13+ of the questions. So I tested the link, and only half of the questions are visible. Once those questions are answered, the system ends the survey abruptly without going to the remaining questions. I can’t even hit the “down” arrow to continue - it just doesn’t show ANY of the remaining questions.
