Issue with 'ticks' disappearing from the design quiz settings causing modules being unable to be completed by staff

Hi Julie, 

Would you mind sharing your project with us here so I can try to replicate the behavior you are experiencing on our end and figure out what's happening? If you prefer to share your course in private, you can open a case with our support team and share your project file there. 

I've previously worked on a project file that showed similar behavior, and I seem to recall that the reason was because the project file had multiple results slides, and disabling some of the 'Submit results' triggers caused the settings in the results slides to change. Let me know if this the same or close to what is happening on your project file!
