Hi,
Would it be possible to have more details about your product & shipping configuration ?
Right now, I can add the product in the cart and see a shipping method during the checkout ("manual" ID 1) ; but I can't confirm that it's a shipping method for "warehouse1" or confirm that the product right is in "warehouse1".
I perform a simple test in my local website and I can't reproduce your issue ; so I think that I don't have the same configuration than yours for some parameters (product, warehouse, shipping or main configuration).
Regards,
