Staff Billing Reports - need to reflect accurately

When I filter by service date, for example to get an accurate account of how much money I made in one week, it's impossible to get an accurate picture, because with however you've formatted the technology, it pulls in anything I've posted during that time. So, if I've posted that I received a payment for a July 23 service date on August 17 when I search the week of August 17, it pulls in that information. But I don't want to see anything related to July 23. I should only be seeing the money I made during the week of August 17. That's what the whole function of searching by date range is supposed to be for.
