Help Fixing a Negative Receipt Routing

We are going through a process of cleaning up our inventory information and find we have several items with a negative quantity in Receipt Routing. It looks like in every case, the same process was done twice. We only have two statuses INSP and STK. When I try Movement and Disposition, I'm unable to move the status forward or backwards. I tried going into the Routing Ledger and reversing it as well. These are old so all the PO's look to be vouchered. Any ideas on what to do?
