[ANSWERED] Player doesn't get kicked if it's walkspeed or jumppower is above the limit?

Hello.

I am currently attempting to make an anti exploit for walkspeed and jumppower for the Player. I attempted to do this, but for some reason, it is not kicking them when the WalkSpeed or JumpPower is above the limit. I am quite unsure why this is happening.

Here is my script (ServerScript):

local Players = game:GetService("Players")

Players.PlayerAdded:Connect(function(Player)
	Player.CharacterAdded:Connect(function(Character)
		local Humanoid = Character.Humanoid
		while true do
			wait(5)
			if Humanoid.WalkSpeed > 30 then
				Player:Kick("Speed Exploit Detected")
			end
			if Humanoid.JumpPower > 51 then
				Player:Kick("Jump Exploit Detected")
			end
		end
	end)
end)

I'm not sure why this happens, and would like some help. Thanks!
