Second Preview mesh vanishes

When adding a second preview mesh to a skeletal mesh, it is only briefly displayed, and not visible as a preview mesh under the socket hierarchy. See video - YouTube

Also, for some reason when i use 2 preview meshes on different sockets, and disable the view of 1, it is still visible.
