3819061 - New Concur Travel - Why did my Amtrak booking failed when the payment was already sent to vendor but received failed email?

Was there recently a new requirement to need the billing address for Amtrak bookings either be it using a Ghost Card or personal card? As we see the bookings fail though we send correct card details to Amtrak. But we receive failed amtrak emails that the payment was not completed. what is the behaviour?
