Wheel not showing in Skeleton tree

Hello, I can’t see my wheel at the physics asset, I only can see “root”, which is the car’s body. I don’t know if I need to change something in UE4 or in Blender, or what is wrong. I just want to add a collision type to the wheels separately to the body.
(and yes, I rechecked the parenting and even used the car rigger for blender to unreal)
(also I reposted this from “Zego-Fr34ks” and hope this one gets more answers
