Canvas not showing missing MC assessments

Community Member

I have students that are unable to see their missing Mastery Connect Assessments in their missing list on Canvas LMS.  I logged in as a student and I see their ungraded assignment on the Grade tab, which includes a passed due date, but it does not show missing. Therefore, the students are having difficulty finding the assessments without having to go through either all the grades, or funding the module it is listed in.  What am I missing in the settings that adds these types of assignments to the missing list?
