Xfinity Paramount + with Showtime subscription missing episodes??

I have been trying to watch the Lioness recently and it is on paramount +. I have the paramount + with showtime xfinity subscription. I am aware this does not let me use the paramount + app, but instead makes the shows avalible on demand under the P + with showtime tab. However some of the episodes are missing? For example i can watch season 2 episode 3 through paramount + with showtime network, but i cant watch half of season 1 or any other episodes in season two. Why is this? Also, for whatever reason, season 1 is completely avalible through paramount on my xfinity mobile app. Why is this the case? It also happens with many other shows. Xfinity clearly has some of the episodes on mobile, why are they not on my tv box on demand? This service is so inconsistent.
