This looks to me like the crew loaded Runway 22L in the Take-off init page and then departed from 22R.
22L at 8,400ft available (vs 12,070ft on 22R) was still likely long enough so the perf calculations came out OK.
As they began the take off roll down 22R the RAAS system would have began squawking repetitively
"On Runway 22R! On Runway 22R!", Warning the crew they were departing from the "wrong" runway.
The crew likely thought "WTF? Why's it doing that?" And sensibly decided to abort the take off and figure out WTH was going on.
