The blend Space is not taking effect

I am doing the “Introduction to Third Person Blueprint game” tutorial.
When playing, I only see the idle animation pop straight into the run even though there is a walk in the Blend space.
Even the video shows the animation poping straight into the run. Is there a way to see the gradual increase from idle to walk/jog then run?
Is there another tutorial that explains how to do this ?

You have to add a Acceleration and a Deceleration value → otherwise the speed will directly go from 0 to 300.

I changed these but still having this problem?

Did you change the max value of the blendspace axis? By default it’s 100, you should set it to the same value as the character’s Max Walk Speed.
