1C-Bitrix. Where are warehouses set up?

Question

1C-Bitrix

Good afternoon. Can you please tell me where the warehouses are set up?
I created 3 warehouses (Inventory>Warehouses). Everything seemed to be okay.
BUT. We order goods. It is only in stock 2. Order placed. 2 pieces.
We go to the admin panel, to orders. And we see that 2 goods in 2 different warehouses. Moreover, these warehouses are not among those that I created.
Where else is information on warehouses indicated? thanks in advance
