User permissions - Allow "Warehouse" for Value "A1" shows all warehouses

Hi all,

I created a user profile, that has only access to stock summary.
It does not have access to items, warehouse, etc. on the whole.

When I click on “stock summary” it doesn’t show anything. Rightly so I suppose?
Now I want a specific user to access only data of warehouse “A1”. So I set the user permissions as follows:
Allow “Warehouse”
Value “A1”

After refreshing, the user can now see all items in all warehouses, as opposed to just the stock in warehouse “A1”.

Does anybody know how to fix it?

Thanks and best,
