I wouldn’t worry too much about it. Sometimes even when the data is correct, and you pop it in the kiosk at SXM, it still sends you to the immigration officer. . At least then you get an SXM stamp in your passport.
I am travelling tomorrow on WestJet 2276. I put the info in last week.
Will be my third time with the system so far I’m two for two
