Stock Quantity per Warehouse selection

Hello,

Please i need assistance.
when I want to do stock transfer of product F from warehouse A(Source) to warehouse B(Destination), I discovered that its the total stock of Product F across the warehouses that shows for selection of quantity to be made as against the quantity of Product F in Warehouse A only.

Same as when I want to create an invoice for product F from Warehouse B, rather than showing the quantity of Product F in Warehouse B only to guide quantity selection, it shows total quantity across warehouses. I suppose this is not suppose to be as other software works by quantity in the warehouse location.

Is there something or settings i didn’t get right? pls help
