Animation Blend Tree: Odd Idle Behavior

I guys,

I have used blend trees quite allot and never had this happen, or never noticed.

I have a 2D blend tree, each direction -1 to 1. With standard locomotion; Forward/Back/Left/Right/Idle.

For some reason, when I go back to Idle (0,0), it sometimes continues on through part of the idle animation.

It's very noticeable as the idle animation has a point where the character looks back at the camera. So to can go from running(looking forward), to immediately flipping their head back at the camera.

Is this normal? Do I have to fix/override through some code?


Thank you in advance
