Issue with trying to implement local multiplayer with controllers with Unity 2018.4,Setting up multiple controllers for a local multiplayer game with unity 2018.4.14

Hello everyone, recently started a game project for a class and wanted to make a local multiplayer like game on Unity but current hitting a wall in development. I am currently using the third person characters/controller scripts from the Unity Standard assets and tried to modify them so that it can work with multiple controllers with little luck. As soon as I move one player, the other player moves as well. So if I can ask is there a way to get them to work with controllers or should I try to make players from scratch?
