Walk animation won't stop looping, Help?

Here's my code

local Figure = script.Parent
local Torso = Figure:WaitForChild("Torso")
local Humanoid = Figure:WaitForChild("Humanoid")

--All cycle animations
wait(1)
WalkAnimation=Humanoid:LoadAnimation(script.WalkAnim)
IdleAnimation=Humanoid:LoadAnimation(script.IdleAnim)
JumpAnimation=Humanoid:LoadAnimation(script.JumpAnim)
FallAnimation=Humanoid:LoadAnimation(script.FallAnim)
LandAnimation=Humanoid:LoadAnimation(script.LandAnim)

Humanoid.Running:Connect(function(sped)
	if sped>0 then
		if not WalkAnimation.IsPlaying then
			--WalkAnimation:AdjustSpeed(/0.1)
			IdleAnimation:Stop()
			WalkAnimation:Play(nil,nil,WalkAnimation.Length/0.3)
		end
	else
		WalkAnimation:Stop()
		IdleAnimation:Play() --When I remove this its fine. But when I add it it does infinite walk cycle
	end
end)

Humanoid.StateChanged:Connect(function(oldState, newState)
	print(newState)
	if newState==Enum.HumanoidStateType.Jumping then
		JumpAnimation:Play()
	elseif newState==Enum.HumanoidStateType.Freefall then
		FallAnimation:Play()
	elseif newState==Enum.HumanoidStateType.Landed then
		FallAnimation:Stop()
		LandAnimation:Play()
	end
end)

For some reason the IdleAnimation causes the Walk cycle to happen infinitely. Also I've already changed the IdleAnimation.AnimationId to the one it's suppose to be
