How long did you drive on them? The truck will show the tire pressure of the old tires for quite a while especially if they are nearby when you start the vehicle. I never bothered trying my 2019 sensors because when I went to the parts counter I was told the parts are different as I described above.
It showed the replacement wheel pressure. My original tires were aired to 42psi on all 4 (after driving) and what the screen showed.
When they swapped the wheels, it updated all 4 tires to different new values (one was 36, two were 38, and one was 37), but only after I was already 2-3 miles down the road. When they swapped back to my original tires, the readings updated back to 41 PSI on all 4, again 2 or so miles away. While driving those 2 miles each wheel had a "-" as if it didn't know the value.
All this was automatic, no re-programming, the truck just picked up the various readings. Tech saw it too, he said he didn't realize they would auto update, as he never tried it that way. But he said makes sense, these aren't encrypted or sending a tone signal, they operate on the same frequency, so TPMS sends a reading per tire, truck listens on that frequency in proximity to the wheel.
Other systems operate differently (especially centrally monitoring ones, where it is not proximity), those have tone or sub frequency so the truck has to "re-learn" where that tire is located, as it can't tell which position it is in.
