Udyr voice bug ( bear stance only )

Hello Riot, I have problem with my Spirit Guard Udyr. He only saying bear stance quotes. And taunts for Nidalee, Anivia, Volibear and Rammus don't works. If I kill dragon, or Baron, he is quiet. If I place the ward, he is quiet, or if I clear neutral jungle camp. If I max some stance, he say correct quote for it ("Flames of the phoenix!" on phoenix, etc.) Please, Riot fix it asap. :/

btw: I'm sorry for bad english, but I hope you will can read it and help me.
