Multiplayer actor spawning problem

Hey guys :smiley:
So, i tried to create a multiplayer game in unreal engine for the first time.
In my game a player should be able to pick up an item. Of cause, this pick up should be updated in both, the clients and the servers game. For that i created the following setup.

The Interact event is basically just a line trace to check for the item, delete it and spawn a new one.
You can see a screenshot here:

Every item is set to replicate movement, on game load and of cause replicate itself.

But with this setup i can not pick up the items on both games. It only works locally. Why is that so?
