Pledge Billing Utility and Closed Batches

We are just getting started on automated pledge billing, and have hit an odd obstacle.  We have a number of custom batch-related reports, and they are hanging up on the fact that when the Pledge Billing Utility runs, it closes its batch without specifying a "closed_by" and "close_dt".  These seems generally like a problem, above and beyond our own custom report issues.  Does anyone know anything about this?  Is it expected?  Fixable through configuration?
