Course Press Unit Questions Disappearing

Course Press Unit Questions Disappearing:
I have entered 12 questions for a new (duplicated) Course. I save after every 4th question, and saved again after all 12 questions and their answers were entered. All my questions and answers were correctly listed on the screen. Then I clicked on the Draft icon to publish the Unit and all my questions and answers disappeared. This has happened twice. How can I enter these questions and publish the Course and Unit?
