FilteringEnabled Code Runs Multiple Times Time When It Should Run Once?

So, I have made a FilteringEnabled walkspeed boost pad. When touched, instead of the person who touched it gets the boost, everyone in the server gets it and it runs once per person in the server. Is there any way to make it run once and for the person who touched the part?

--Server script
local Button = script.Parent.Button
local Event = game.ReplicatedStorage["Remote Events"]["Bonus_Walkspeed_Pad"]
local Duration = 3
local Boost = 2


Event.OnServerEvent:connect(function(Player)
	local Character = Player.Character
	local Humanoid = Character:FindFirstChild("Humanoid")
	Button.CFrame = Button.CFrame * CFrame.new(0, -0.1, 0)
	Button.BrickColor = BrickColor.new("Dark stone grey")
	Humanoid.WalkSpeed = Humanoid.WalkSpeed * Boost
	wait(Duration)
	Button.CFrame = Button.CFrame * CFrame.new(0, 0.1, 0)
	Button.BrickColor = BrickColor.new("Bright green")
	Humanoid.WalkSpeed = Humanoid.WalkSpeed / Boost
end)

--Local script
local RemoteEventFolder = game.ReplicatedStorage:WaitForChild("Remote Events")
local RemoteEvent = RemoteEventFolder["Bonus_Walkspeed_Pad"]
local Model = game.Workspace["Button FilteringEnabled"]
local Enabled = true

Model:FindFirstChild("Button").Touched:connect(function(Hit)
	if Hit.Parent and Hit.Parent:FindFirstChild("Humanoid") and game.Players:FindFirstChild(Hit.Parent.Name) and Hit.Parent:FindFirstChild("Humanoid").Health > 0 then
		if Enabled == true then
			Enabled = false
			RemoteEvent:FireServer()
			wait(4)
			Enabled = true
		else
			print("Already Fired, waiting for cooldown.")
		end
	end
end)

Yes there is, Try using Firing a client only for the player,which raises the walkspeed.
