I have looked around for an answer to this, but can't find one.
When I got to associate a blueprint with a course, it won't give me a complete list of available courses. It will show me fully-populated courses that I don't want to associate, but it won't show me the empty courses that I do want to associate. I have tried publishing them, unpublishing them, removing users, and creating blank courses with nothing in them. All to no avail! I don't know what the secret is. Anyone have ideas?
