I was following it earlier and the destination seems to be a bit iffy.
I've been at Washington Depot twice this week on morning run-out, and noted the problem with both 8270 and 8271.
Observing from afar; it looked like the destination glass needed to be cleaned, rather than an issue with the destination display itself.
