Scaling Up achievement (SP Custom Outfit) is only 12CDMG for real?

[prietess]

Why on earth does Stonescale Passage Challenge Mode outfits not giving 5AP set?

The achievement for other challenge mode outfits (bought using challenge mode tokens) are giving 5 AP (except DST?).
Even the achievement from brood chamber custom outfits is giving 5 AP, Stonescale passage is so long after Brood chamber.

SP was one year ago.

BC was like??? 2 years +??? 

Doesn't make sense??
