Lease invoice headers pulling abnormal amounts

Summary: Our lease invoices are creating the correct line amounts, but abnormally large header amounts. For example, we generated invoices on a lease that has a base rent of $12000. Each month invoice had a line of $12000, as expected, but then the header amount was reaching over $300k. Any advice?
