4 Player split screen controller problem

[Xeo The Fresh Reindog]

So I have been copying the main player four times to make a four player split screen level. It all plays fine besides one thing, the top left screen. When I play a game and use any controller the player will move for that screen plus the player in the top left screen will also move. Do you know why it does this and how I can fix it? Thank you for everything! I hope this made sense

You just copy the two player split screen in the editor until there is 4 players
