Stuck with warband item

I opened my own warband chest and borrowed an item from it. I had upgraded it to rank 2. I later found the same item in a dungeon with better stats so now I don’t need the warband item anymore. Unfortunately I can’t return the item because it’s upgraded, I can’t stash, sell, salvage, or destroy it since it’s a warband item. So now it’s just stuck taking up space in my inventory.

something similar happened to me, I returned one item (pants) to the warband stash and then borrowed another (chest), now both items in my inventory have an icon as borrowed from the stash… so I cannot inherit an essence on the pants now because is also “borrowed”
