My AI Will Move but wont play the animation

I am trying to make a Animatronic Play a run animation when ever his max speed gets to 600 with a blend shape Anime BP But when ever it goes back to 100 it plays the walk.

But it doesnt do that.It doesnt play the animation at all.

I am using AI without black boards.

When are you calling on the blendspace?
If you’re using it just for walking/running, I recommend using a 2d blendspace.
