Nameplate problem

i have problem with my own avatars. the nameplate is really high above the avatar and i dont know why. can anyone help me?

Either you have something above your avatar, or the origin of the armature is higher than it should be

The name plate is roughly .5m above where your viewball is placed. You probably have the position too high in Unity. Check the avatar descriptor and lower the viewball to be between the eyes or so.
