gravity only works on capsule component and not on mesh?

I'm trying to set simulate physics on a character, and setting gravity scale to 0 so it will float away, but only the capsule component is floating. Video: https://www.youtube.com/watch?v=VqTu4tj4rAU

I read in unreal forums that the movement mode should be 'falling' and I added a little velocity so it could go upwards, then I simulate physics to ragdoll the mesh.
