I am trying to deslect all inventory items from various stores and only leave them linked to one store.
I have used 'Edit, Inventory, Item File Chosen the item and selected 'Slect Stores and used the 'Deselect All' option.
The error message 'This store cannot be deselected as it is in use' appears.

How do I resolve this as we are no longer using multiple stores for inventory?
