So, in the first PAW Patrol movie, Liberty got her own vehicle, and it had the number 22. And in the second film, Everest and Tracker were literally on Ryder's pajamas in two scenes.

I don't know if that is true or if it's just me, but these imply that Everest, Tracker, and the other members do exist, but the movies were set in Adventure City. So, as a result, they were not there in the movies.
