When a Unison course is opened and a quiz is edited (options, questions, labels, etc), the changes do not appear after the course is closed and re-opened.
Why this Occurs.
This occurs only the quiz is being changed. This creates an error that makes the main save button and "save when closed" function not work.
1) Edit the quiz page how you want it
2) Click the "save now" button on the right side of the screen. (See screen shot)
3) Close the course
4) Re-open it
The changes made should still be there.
