Why is my team changer script not switching players properly to their teams??

So I made a GUI for changing teams. I have the script to change to the "Electric blue" team and the "Deep orange" team. It shows that it switches you, but in the game it's only you that have switched teams even though others have probably. Also, your chat is deep orange, since when you spawn in your team is automatically deep orange.

The script is in StarterGui.ScreenGui.Frame.Textbutton.Localscript

Script to switch to the Electric blue:

local player = game.Players.LocalPlayer
repeat wait() until player.Character
Character = player.Character
Character:WaitForChild("Humanoid")

script.Parent.MouseButton1Click:connect(function()
    player.TeamColor = BrickColor.new("Electric blue")
    game.Players.LocalPlayer.Character:MoveTo(Vector3.new(-103.8, 94.62, -159))
end)

The script for Deep orange is the same, just replace line 7 with player.TeamColor = BrickColor.new("Electric blue") with "Deep Orange"

I have a feeling it has something to do with WaitForChild, but I wasn't too sure, so I added the code in lines 2-4

EDIT: I have filtering enabled on, but it's still not switching the player's team's. Here's my local script:

local player = game.Players.LocalPlayer
script.Parent.MouseButton1Click:connect(function() --Put the script into the textButton you want to click
    game.ReplicatedStorage.RemoteEvent:FireServer()
end)

and here's my script that receives the remoteevent but it doesn't switch the teams still.

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player)
    player.TeamColor = BrickColor.new("Electric blue") --Change the name to the team you want.
    game.Workspace[player.Name].Torso:Destroy() --You can change it so that the player doesn't die to whatever you like.
end)
