Blender Custom Rig animations are weird when imported to Roblox Studio

Hello,

So I’m trying to import enemies along with its animations I have in Blender, however as I preview the animations with the “Import 3D” feature on Roblox, the animations are imported looking a bit goofy for some reason even though everything is fine in Blender. Here’s a clip of it in Blender:

But when I import it into roblox it looks weird and it looks like everything moves along the main bone

Does anyone know a solution to this?
