Unable to call events from blueprint interface like in past UE4 versions.

I’m not able to call events through a blueprint interface in the animblueprint like I was able to do a few versions ago, is there another way of doing this?

For more context of what I’m doing, I’m following a tutorial, found here, issue found at 7:50: 💢 UE4 Climb System - Tutorial - Part 1 - Grab & Climb-Up - YouTube
