I've found extraneous glitches and extra letters, more so recently.
Probably the worst was a couple of months ago when I didn't get pre-check on my boarding passes. Then TSA flagged an issue. Seems somehow my DL profile was corrupted (they suspect it happened when a counter agent did a passport scan) and I suddenly became 102 years old! It took about ten minutes to correct the profile and reissue correct boarding passes.
