Problem with fire/walk transition

Hi.

I need help, please.

I had 3 animations: idle, walk, jump. I added fire animation to my player, and every transition works fine, fire/jump, fire/idle, except fire/walk.

The problem is that when my player walks and in the same time I hit fire button, I see that my player have 4 hands, two for walk anim, and two for fire anim.

The parameters are: Speed(float), IsGrounded(bool) and Fire(trigger) I have two Layers:

Base Layer The transitions are:

Idle -> Walk: Speed = Greater 0.1;

Walk->Idle: Speed = Less 0.1;

Walk -> Jump: IsGrounded = false;

Idle -> Jump: IsGrounded = false;

Jump -> Idle: IsGrounded = true;

Fire Layer The transitions are:

new state -> fire: Fire;

fire -> new state: exit time(0.1).

All my transitions have no exit time, except one(fire -> new state)!

Can someone help me with this one?

Thanks.
