Interesting! When I asked about the missing PreCheck I was told it was because of the SSSS at LHR and should resolve itself en route once systems had been updated that I had been screened and was on board. At the end of the day PreCheck is never guaranteed so I suppose part of it is randomized to keep you guessing
