Hi Jaclyn,
Looks like it might have to be resolved with Microsoft ticket.
If you are a fighter and dont want to let the "system" get one over you, I suggest you try the following in a copy of this database. I would not suggest doing it in Prod unless you have proven it in a copy of Production. I have done the following several times before the clean-up Cancel was added.
1) Create a new temporary Location profile for Users;
1.5) Force log-out any Workers sessions (work user sessions).
2) In Warehouse Management parameter, temporarily change the Location profile for Warehouse worker to that new Loc Profile
3) Since the location is no longer a User location, go to that troublesome Location (Kionnidis) and adjust the quantity for the exact inventory dimensions on the InfoLog by +.062
4) Revert the Location profile on Warehouse management parameter to its previous value
5) Try to complete the work (or cancel).
6) Hopefully it will clear, if not the new InfoLog will let you just how worse you made it and you know a little more for a second attempt (because you are a fighter!)
Much much better and safer to do in a Prod copy.
