Copied Course Dates in Canvas
Cause
Your OWLv2 activity links have Until dates.
The Until dates in your old Canvas course were copied over to your new course. Since the Until dates have passed, you cannot update the due dates.
Resolution
Remove or shift Until dates on OWLv2 activity links so you can set new due dates.
