Dashboard Tracker Filter Field always displays false

We’ve customized the sales order shipment status dashboard. After we input the order number and then move to another field/filter, say, CustID or Ship Date, etc., the Order field always displays false (pls see the plot below). If we click on the field again, it can display the order number. Anyone has this experience and know why? Pls help. Thanks.

In the customization Tools, when you select the box is the value empty?


Hi Cass,
Thanks a lot. Yes, the value is empty for the box.
