Labor Edit Report Missing Department

Has anyone else had this issue? We run the Labor Edit report and
the department is blank. So far it's only happened on our Indirect
codes but it's a mystery. We called tech support and they said it
was the way our users were entering the data. Tech support said the
users were not double clicking on the workcenter or not advancing
the tab to get the department to come in. I've tried to recreate
this by just typing in the workcenter, not tabbing forward and then
pressing the ok but I still get a department.

Any and all help will be appreciated. We're on 6.1.
