Clean c++ project multiplayer not working

I am not sure if this is a bug or if i am missing something terribly obvious here.
When i make a new c++ FPS project and try to simulate multiplayer, i cant see the weapons being replicade BUT the collision and movement are working normaly.

This is very strange because if you do exactly the same in a BP FPS project everything works as it should…

Did any one else run into this? is this a known bug? some one point me in the right direction please…
