We've set up Apple School Manager and are importing users and classes into JSS. In this phase, we're testing with just one course. We have put a couple of classes in ASM, and have linked them to this 1 course. (That means: there's only 1 line in the courses.csv file I've uploaded to ASM.)
Now, when asking JSS to import classes, it lists 3 instances of every class, each linked to a different course ID (see screenshot). But there is only 1 course ID in ASM!
The question is simple: where is JSS getting these extra course ID's, and how do I get rid of them?
