Root part/bone not animated

[de_ew (and9ew)]

Hi, I am not an animator, but I am trying to export mixamo animations into roblox studio and I am encountering a problem.
This is the tutorial I am following: https://www.youtube.com/watch?v=rplF-mKRX2A
This is the mesh I’m trying to work with: Frieren, from 葬送のフリーレン - Download Free 3D model by ChamberSu (@chambersu1996) [a65166a] - Sketchfab.

I inserted the mesh in mixamo and the animations load properly, but when following the tutorial and trying to insert them inside robox, I noticed that the root part (or the pelvis bone?) stay in place. Let me give an example: if I choose a jumping animation it does not actually move the character up, same for others, see screenshot and video below.

Note: This is a similar thread I saw but the solutions didn’t work for me → Issues with custom rig animation

With roblox you cannot have a bone named “root” take the model into blender and change it to something else. I change mine to “Armature” then export and reimport the new rig into both mixamo and roblox.
