You reserved in Dedham but did you have a PA address for delivery? I wonder if that made a difference...
The address in my account was set to a Boston MA address when I got the config invite email. Once I logged in and went through the deferral (waiting for AWD) and it asked me to confirm the name and address that I would be using to order/register the car and then I changed from my MA to PA address since I plan to order and register the car there.
