Costing Period Close - Completed Work Order not Closed

Summary:

Running into a Period close error saying Completed Work Order Not Closed, but when I look at the work order in Manufacturing Execution is shows closed. When I look at my Work Order Costs in Costing, it shows status or work order as complete. All Production Transactions have been transferred to costing. Any Ideas on how to correct this?
