Has anyone else experienced this? :

My son and I are on a group itinerary with 30 other folks. When I look at my seating choices online, I see them normally. However, when I log onto my son's account to view HIS seats, it shows MY seats and actually shows MY name and FF #. I have tried to click that "change FF#" button to no avail. I have called and Delta assures me we both have unique seats and that everything is fine. On their screen it shows us as 2 unique folks with 2 unique seats as expected. It just does not show up on the Delta website on my end.

I should add that we both have the same name, except my Delta name in the system is Jr. and his is "III". The reservations person assures me that this name differentiation is accounted for and shown on Delta's screen.

Is this just a computer glitch in their system or should I be worried?
Any thoughts?
