I have a flight missing on one of my bookings, OGG-LAX. The booking also won't load on MMB. I've spoken to the Gold Line and been told it's all ticketed correctly, and the fact it won't load could be to do with the way AA have created the booking/itinerary and it not being compatible with BA's systems. Other bookings made on aa.com all display correctly. A quirk of the system?!
If you want some reassurance give the silver line a quick ring to reconfirm it's all ticketed correctly, but I'm sure you've nothing to worry about.
