Mystery Talents

Ok, so today i just breed my Pure S Joey in which it had the Inverse Talent, which i bad since I'm planning on using it with Sword Dance skill, i thought of changing it's Talent by reactivating it on the Monster menu, but it didn't change resulting in a waste of a Simple Rune Gem(Yes even if it's just Simple it's still a Rune Gem)

I just wanted to know if a monsters talent can be changeable or not , since the Activate Button is still there while a monster already has a Talent.

Want to know if it's a Bug or Talents are just Unchangeable

EDIT: Nevermind, i gambled my second rune gem and it was changed

you bred a joey to S.... just why?
