Similar situation - my guess is the mapping is messed up on some fares with how they display when you look them up again. I have a few tickets that I swore were booked in Economy Flex and when I go to manage my bookings show as Standard now. I took CC's advice above and looked at Saudia with my ticket no. and still see all the legs showing as FL fares. I will wait and see what ultimately posts and then write in if I need the mileage adjusted.
