OK... I've seen this "AF1" weirdness before but today was even weirder

Biden was near Pittsburgh today to talk about how he is going to crush the economy.
He was supposed to depart at 6:15EST according to the official schedule
https://factba.se/biden/calendar/

Tail # 09-0017, 757-200 that we've seen Trump on many times, normally designated as AF1, once again, shown as "n/a" on flight tracker. That has been consistent.
When Biden and Harris flew to Georgia for the CDC talk, they flew on separate jets, as expected. Harris' flight was designated AF2, as we'd think it should be.
Biden's flight was "n/a", again.

Back to today, check out the flight path of 09-0017 (designated n/a, NOT AF1, again)
Leaves Joint Base Andrews and flies OVER the Pittsburgh area at about the time Biden is scheduled to depart. Never lands, maintains altitude of 25K ft. (the flight path color designates attitude) and flies back to JBA.
This is beyond baffling. Why? Even if it is all theater, no la

Update.
Another jet designated n/a left Pittsburgh just after my post.
This would be another potential "AF1" carrying Biden, though not designated as AF1. Tail#82-8000
Makes a little more sense

The other just did a flyover?🤪

Anyone know what is going on with the lack of AF1?
Yet Harris flies and it is designated AF2?
Mind continues to be blown
