Anyone know what this could possibly mean? I went to Jl's website to check on seating for my F flight in July. When I entered the booking info in the manage booking I get this message:

Please confirm the following.

• Error: We sincerely apologize for the inconvenience.
  The schedule of your reserved flight has been changed. However, reservation details cannot be displayed due to the following reasons:
  • Reservation includes an upgrade
  • Connecting flight must be changed due to a flight time change
  • Flight route or seat class has changed

My return flight booked as a separate booking displayed my booking info no problems. Both award bookings were made with Cathay Pacific Asia Miles.

Update 1: I just checked my email I received when I booked the flight and the connecting flight time has changed by about 20 minutes. I'm hoping that is what this error message is about.

Update 2: contacted Cathay Pacific with their chat feature. Agent verify the connecting flight time change of 20 minutes. Asked me if I was ok with it. She updated the reservation and I was able to access the booking information on JL's website.
