The item was released out of restricted subinventory and now its stuck in manage pending transaction

Here is the summary:
1. Item was released from a subinventory that Restricted Subinventory status
2. This was only a one time thing, and we have not been able to replicate the issue
3. The status for Order Line 1 is Closed in Order Management, but it appears to be stuck in Reservation on the reservation screen.
4. The same order line also shows a Manage Pending Transaction status on the shipment lines page. However, we can't find a pick slip for this order.
5. Even if we select Restricted Subinventory on the sales order line, the item is back-ordered when we create the pick wave.
