Why are charges different in the Accounts Receivable Report if the Simplified AR Report checkbox is selected?

Selecting the Simplified AR Report checkbox in the Accounts Receivable report creates a simplified report that shows charges at the Service Level rather than the Insurance Payer level. If the Simplified AR Report checkbox is not selected, a non-simplified report shows charges at the Payer Level.

Example: If there is a $100 charge with a $20 copay, the simplified report shows $100 charged (no payer info), and the non-simplified shows $100 to insurance and $20 to the client as two different charges. There are adjustments that make up the difference, so the net should be the same in both scenarios.
