4.27 weird animation transtion blend issue

I’ve been having an issue for months and I don’t know how to solve it, there’s a weird issue with animation transition blending where there’s a small pop, the character just moves down for a moment during the transition from JumpEnd to Idle/Run.

Doing some research, I found this thread with a similar issue but with a much older engine version, it’s supposed to be fixed but I still have the issue in version 4.27.

My animation blueprint is setup just like the third person template, here’s a link to a video to help explain the issue: Unreal Engine 4.27 Animation Bug - YouTube

I’m using animations from 2 Assets Powerful Sword Pack in Animations - UE Marketplace

What could be wrong here? I’m having the same issue with other animation packs as well.
