No idea what the problem is, but if you're close enough to the airport to swing by today it might be worth the time to get this sorted out and have your BP issued. I recently went by the airport the afternoon before departing on a very early morning flight to start an international trip so that I could scan my passport and be issued my "real" boarding passes. It made the next morning much less stressful because I've had trouble with international checkin in the past. Good luck!
