If a course has only one offering and one class, if a learner enrolls at course level, (s)he can enroll automatically to that class even if this class is in the past.
We discovered this behaviour for a class for which the enrollment end date was not specified.
When the learner drills down to offering then to class, those that are in the past are not accessible in the catalog (as a learner).
Is this an expected behaviour? Did anybody else experience this?
