Interface and animation buleprint

The project I’m working on in ue4 is using a interface as a cast for the animation bp. I was trying to use it to work with climbing system that was made and got don’t know why the movement for moving left and moving right works but won’t connect with the animation bp. It uses a event with a set timer by event and a time handle notify. The notify contains the script to move left or right when you press the A or D key and works for multiplayer but when I try connecting a interface to tell a part of it to move with the animations the animation won’t work with the movement. I tried using montages to work but it seems there is a bug that continues to run after you ended the wall climb moving left or right. Is there a way to connect the left moving and right moving climb with the interface and the animation bp? I’m using events to avoid ticks, using interface to avoid casting. Any information on this is extremely helpful and thank you for your time.
