Sapphire Set Dance

Leviath_Imp - Lost City

Hello to all pwi community as well as the GM's reading this post:

I received a sapphire reward from a pack and decided to get the set because its fashion and what else to do than try it out?
I ended up loving it (full black now, ouch 27 dyes there)
However, when I click dance, the sapphire dance doesn't show. I simply just stand there without my weapon. Is there some setting that I did wrong or something?
Some help would be greatly appreciated. Thank you.
