Default Address Question

On the sales order I have multiple addresses that I can send an address to. Changing the Invoice account is not an option. I tried changing the primary address, but it looks like the default address is controlling the address that is used.
I entered new sales orders after changing the Primary address but this did not help.

How can I change the default address by customer account?

Which address do you mean? The delivery address? The invoice address?

By the way, which version of AX are we talking about?
