Static Mesh Actor not Replicating

I have a VR Multiplayer where I have a pickable (from the VR Template). But it does not replicate. Under Class Defaults I enabled every replicate option but when I am on the server only I can see the cube in my hand not the other player. what am I doing wrong?
(I already managed that each other can see the hands and head. I take the logic from the collab viewer example and it works) But not with the pickable cube. I don’t know what’s wrong here
