Using the web version of Canvas, I'm having an issue assigning a Canvas Classic Quiz to both a class section and some individual students.

Then I save the Quiz, Canvas splits the class section and the students into different Assign To blocks. This alone is fine, but the issue is that the class section Assign To block loses its due dates/times and thus doesn't show up in the students' to-do lists and Calendars.

This seems to be a glitch. Anyone else having this issue or understand what is going on? Thanks! Dan
