Receiving Clerk Dashboard - Receipts with no bills - Seems incorrect

Hello,

On the standard Acumatica Receiving Clerk dashboard is an item called “Receipts with no Bills”. 

I examined the GI behind this and it seems incorrect.  The selection criteria is as follows.

This seems incorrect as it is checking a text field that seems unrelated to determining if there is a bill.  While it says “InvoiceNbr”, the field is actually the Vendor Ref. when you examine the data.

Am I correct that this is bad logic?

Does anyone have a suggestion for proper logic to display “Receipts with no Bills”?

THANKS!!!
