Have an upcoming ticket and one of the segments is showing up twice in the reservation, with a notice check connection time and change airports at PHL. One of the flights have the seats chosen and the other one does have it and won't let me change seats.

Not sure if this is a one time glitch or if it's happened to someone before. Spoke to the EXP desk and they said they didn't see anything wrong on their end but that the rep had gotten a similar call earlier today. Hopefully it won't be an issue on the day of travel. Any thoughts or suggestions are welcome.
