1: Made it so that order date in all instances was changed to staff_fields_order_date to reflect the change we made on the orders list. 2: Made it so that show only empty worked with order date. 3: Fixed issue where clear button wasn't showing the start date and end date if clear button was pressed when they were hidden. 4: fixed issue where null2 checkbox was not being properly set when loading the search page. This should fix bugs we encountered
