I have a quiz in my class which most students have already taken. I have since gone in and changed who it is assigned to so that only a subset of the students are assigned the quiz. Now this quiz shows up incorrectly in my Grades section at the very end, even though I've sorted by date due. Additionally, when I visit the quiz it says it is assigned to no students, although it is still assigned to half the students. In the calendar it appears at the correct date, but also says "no students".
When I reassign this quiz to all students, it sorts properly.
I do not appear to have the ability to submit a Canvas ticket, so I am posting this here.
