Why wont Gradebook auto fill MISSING items after the due date

[whited06]

Following the online directions, my assignment is ONLINE submission, Past the Due date, but still does not auto fill all unsubmitted items as "MISSING"  I can get it to work if I manually score each students' work as "MISSING" on the drop down tab, but the gradebook does NOT auto score missing work as MISSING.   What do I need to check so I can fix this?

also, how do I contact an actual person for support with this product?
