Be that as it may, I had TSA PRE on the BP printed at home, then disappearing on the BP printed at the airport (human checkin), and appearing again at the kiosk.
I suspect yet another experience enhancing software feature.
If you check in using a mobile device, the boarding pass shows the TSA Pre check. It does not matter how many times you view the boarding pass or how many times you have to show it to access the priority lines and agents, the boarding pass retains the TSA Pre check symbol.
