Rock Climbing Wall while owning Snowy Escape

I have noticed that the rock climbing wall from the fitness stuff pack still registers as fitness even though you own the Snowy Escape Pack which has the rock climbing skill. And while I under stand this for base game, I think there should be something that switches for people who own Snowy Escape as this is actually a skill. The rock climbing wall is a at home tool for sims to develop that skill.
