Past Due Fees

So I’ve been setting up a view in my users section for students that owe fees. When we create the fee, it shows up in the view, but I’d like to filter out those fees for the ones that are past due by 30 days so I can print a reminder statement to send out, but when I try, I am not getting any invoices show up.

When I look at individual students, I see the fees showing as past due, but it’s not showing up in any filter or view I create that references the past due that I have set. 

Am I missing something?

Thanks,

Matt
