It works for me:
1. I Export "Object Inventory".
2. In the Scheme panel of the Dialog, I change "Object Inventory" to Object Inventory2".
3. I import the XML I just exported. A new Scheme named "Object Inventory" appears in the list. Also, I have the renamed scheme named "Object Inventory2".
Works both in AC18 and AC19.
