Switchable cross hairs multiplayer Problem

Hello I am currently looking for a system to change crosshair I managed to create it by pressing keys that change them. But my game is multiplayer and I have a problem it works very well as long as no player joins but if a player joins the crosshair is like duplicated which creates two crosshairs one fixed impossible to modify and another modifiable by the keys. I want to note that this is not related to a HUD because I removed the crosshair code from this one. Do you have any solutions or another way to do it?
