Rma Status Inventory Is Not Editable


The default RMA request statuses INVENTORY is not editable, for example, Request and Approve Status have increase inventory, so i dont want to have inventory to increase for any reasons because i know for sure most of the return will show USED or Defective and cannot sell as New. So i would like to change those two status to decrease. I would rather to let seller to manually change the inventory.

So can anyone can help me with this? or Maybe it is a bug?

Thank you so much
