Have you double checked that you've filled in the address field in the APP data sections along with your passport info?
Sometimes the field where you enter the 2 digit state code eg CA for California is not completed so you might need to enter it again.
You're not seated in exit rows on any of the flights are you?
I don't bother doing OLCI if I'm seated in an exit row. When I fly to the US I put my Canadian passport info in the booking (no ESTA required), maybe the system flags me because of that. No clue. I'm flying to the US next week and again in early January so I'll make sure the state is entered correctly.
