pet evolution

i have recently been lving my pet to get it to evolve into playfull/aggresive, and it got to lvl 11 and didnt evolve. does this mean that it will only evolve into dire/hearty at lvl 15 or is it just staying no prefix because thats the way i play with it.

also its a phoenix, i dont know if that rreally matters but maybe they dont evolve, i dont know.

thnx

nvm, the game just didnt update the name until the next time i went outside.
