What would cause all of the past due assignments in my course to show up as missing even if they have been submitted and graded?

In my gradebook, they are not marked as missing. They show a submission and have been graded. 

In the student's canvas account they show as submitted and graded.

On the parent app they show as missing unless you tap on the individual assignment and then it shows as submitted and graded.

Please help. Something isn't adding up.
