Interesting. I think I did book that CS trip via the app after I got annoyed with Chrome not working. That would explain that.
Still, if it's confusing for me, it's something Amtrak should address, because regular people have no hope of understanding it.

It sounds like the 3 front-ends (the website, the Android/iOS apps, and the one the CSRs use) feed into ARROW, the backend system that creates/contains the reservation, but the information is not uniformly populated back to the other front-ends.
