Certain Demands do not show in the Program Workbench
This was happening due to the Demands already being turned into Project records.
The Program Workbench will show only Demands in the State of either "Qualified" or "Approved" and needs the Start Date and Due Date populated.
Some, however, will still not show up if they have a related Project record associated with them. The Project will show in the Program Workbench instead.
