When we copied a series of questions from one course to another new course, the graph doesn't display.

To explain what we did. We set up a course using Stack with the JSX Graph plugin and created a quiz for the students, the quiz has around 15 questions. We ran this for a semester and then, at the start of the next semester we wanted to reuse the material so tried to copy the course from last semester into new new course we created for this one. In the process, all the materials came across, but when we open the quiz, the graphs do not display.

We then tried to back up the original course and restore it in to new one, that too failed to display the graphs. We then tried to backup and restore just the quiz content, that too failed.

The only approaches that seem to work are to create a new quiz and pull in the questions from the question bank. This, however, is a rather long winded way of having to do the job. The other option is to backup and restore individual questions, but that too is rather long winded.

Any thoughts would be appreciated.
