One of the teacher users of our Canvas recently reported that his Dashboard's To Do List didn't show the items from some assignments that have the due dates set in this month and he hasn't submitted to that assignments yet.

But the To Do list from another student user of the same course show those To Do items.  But this user isn't assigned with teacher role of any course.

It seems that users with teacher roles assigned are having different To Do items when compared with the users who don't have teacher role assigned.

However, from the testing site, the To Do list of the same user with teacher role show the items that are missing from the production site.  And there are Teacher To Do list and Student To Do list in the testing site while only one To Do list is found in the production site.

Is the To Do list in production site working properly?  Thank you.
