Climbing problem

Hi all I’ve a problem, I’ve followed this vid 💢 UE4 Climb System - Tutorial - Part 1 - Grab & Climb-Up - YouTube but something goes wrong. Honestly I’m on it from two days and I have no idea how to resolve it. Someone know how to fix it?

Here the problem.

Maybe the problem is thee root. Actually I have problem to make a workable rooted animation.
