I have this problem. When you set dates in a course. Canvas has different behaviour if you access as Student or as a Teacher:
Students will see the course as past, present and future depending on dates. (CORRECT)
Teachers, courses marked as present or future, you will ALWAYS in my courses as “current courses” and NEVER in my courses as past. However, future courses will be shown as future.
Why the same "past" course it is shown as "past course" to the students and not to teachers?.
