Deform Fade In, Fade Out isn't working on front leg

I’m doing a tutorial here: I am unable to get the Deform Fade In, Fade Out to work on the front leg. It works fine on the back leg. Can someone tell me what I am doing wrong?

I later had trouble with the front leg following a pole target. (not included here)

Blend file:

Foot.F.L needs to be a connected child of that bone. It is currently offset. Ease Out controls a curved b-bone’s transition to its connected child; this bone currently doesn’t have one.

Thanks so much! I must have done that by mistake when I was unchecking the connected option for the shin bone (per the tutorial).

Yeah, probably you meant to do it for the ik target and accidentally did it for the foot as well.
