Why? The reason some of Ash's reserved Pokémon did not physically in the Journeys series, thus far, is because the the animators and writers did not actually want to add too many of Ash's reserved Pokémon in the animation frame. Do you think that all of Ash's reserved Pokémon that did not physically appear in the Journeys series will physically appear in the future Journeys series episode? Why? Please let me know, thanks.
