Kaina Bugged?

[Kirby_Z]

I have notice that the skill Kaina seems to be bugged or disabled. Im above Lv 70 and Im suppose to have my ESMA,ESTIN and ESTUN sp cost reduced a 29% according to the skill description but that is not the case, my sp cost is still the same(30sp for estin and estun, 80 for esma) Can somebody plz look at this?
