Hi Alan,
Perhaps it's something else, just for thought. At 1267 MHz frequency is important and with the higher Doppler shift and perhaps other slightly stronger or closer to center frequency uplink signals might be captured. AFC favors stronger, at least fairly constant strength signals and those closer to the center frequency. You may have enough power but are just enough off frequency to be bested by other signals, off frequency can be because of PC clock, lat/long (your QTH) in the tracking program, the accuracy of your transmitter, and items of a similar nature.
I have spent a few passes over the years being off frequency or even stupidly off frequency or even off (wrong) band, wrong Doppler.sqf line selected in the CAT window, no/wrong CTCSS, or forgot to engage antenna tracking, that kinda stuff that just happens. Sometimes the cats turn off the radio when I'm not looking, just before a pass. Nobody knows about these problems though because I haven't told anyone, if somebody asks where I was I just say like "no, I didn't get on for that pass".
