Blueprint actor not moving for other player

Hi,

I hope somebody can help me in the right direction, since im getting stuck at this multiplayer problem.
I made a simple switch that moves a wall from left to right.

When I play this in the viewer (only with 1 character) everything works fine.

When I set the number of players to two, when one of the characters pushes the button the wall closes as it should. However the other screen does not see this wall moving and can just walk through it since it does not see it is in fact closed.

Hereby I will add the pictures to clarify the problem:

This is the view for the first character. The capsule is the switch and the rectangle is a wall that comes out of the other wall.

Here I close the wall by pressing the button

This is how the 2nd character sees the situation. For this screen the wall still seems to be in the old position.

This is the blueprint for the button

This is the blueprint for the wall

I hope somebody can help me in the right direction.

Thanks in advance!
