Why is the velocity length values very weird?

I’m fallowing Third Person Lessons on youtube and I’m at point when Velocity Length is driving blend space. The problem is that when I’m using Behavior Tree Move To velocity values are really weird.

As you can see it isn’t slowly going down so blend space is moving from one animation to another in couple of frames. Another thing is that it’s 0 for couple of frames (can’t see that the character stops but can see animation change for 4-5 frames).

Anyone can help me out? I’m doing everything the same from Third Person Tutorial but I’m moving AI character using Behavior Tree MoveTo.
