You have set up an external tax determiantion rule for state CA (in country US),  where jurisdiction rule is set as ST (Ship To). Additionally Vertex activated in the system.

In the sales order here, the sales unit is in State/Country=CA/US and ship to country is in Brazil. This triggers the external tax determination and leads to consider Brazil, but with Vertex this won't work.

The intergration scenario (External Tax Determination + Vertex) is not supported.
