Why are these production graphs different?

The Production Drilldown graphs show the same total amount but are classified differently regarding Hygiene and Doctors. 

Users might have noticed why the drill-down visuals in the Home-Production panel have different dollar totals when categorized.

If desired,  the Provider Type can be changed via the drop-down menu in the Settings- Code Settings page.  

In addition, some offices will have created a "virtual" provider in their PMS software where procedure codes can end up being assigned to a non-existent Doctor vs who should get the production credit.  But that amount would have been shown as Doctor production in a Production by Type graph.
