TWC TV and TWC Cable have different offerings? - TWC TV and Apps

So on all our devices we see listings for Showtime's Penny Dreadful. On our Cable Box we only see season one and two, but the Mobile and Computer show season three (and we can watch it).
I have re-booted the cable box.
What is also weird is that on the computer I have the option to watch season two episodes on the TV, but not seson three episodes.

This question is about "TWC TV and TWC Cable have different offerings?", with Time Warner Cable TV and apps.
