Animations not working correctly after morph?

Video: https://youtu.be/eXRpUMYFNvA

Hello all, I recently made a morph script, but for some reason, the arm animation is odd, and when a gun is equipped, the arm enters a weird position. Code below for the morph.

Morph Code:

-- Scripted by ItzHiimnew for Prometheus Labs

local MorphName = "IA"

local MorphPath = game.ReplicatedStorage.Morphs.IA -- path to the morph

local ShirtId = "rbxassetid://338740550"

local PantsId = "rbxassetid://338750779"

-- done set up

local Debounce = false

script.Parent.Touched:Connect(function(hit)
	if Debounce == false then
	if hit.Parent:FindFirstChild("Humanoid") then
		Debounce = true
		local humanoid = hit.Parent:FindFirstChild("Humanoid")
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		local clone = script.MorphGui:Clone()
		clone.Shadow.LoadingText.Text = "Morphing into "..MorphName.."..."
		clone.Parent = player.PlayerGui
		clone.Shadow:TweenPosition(UDim2.new(0.404,0,0.782,0))
		
		
		
		wait(1)
		
		local WalkSpeed = humanoid.WalkSpeed
		local JumpPower = humanoid.JumpPower
		humanoid.WalkSpeed = 0
		humanoid.JumpPower = 0
		
		wait(2)
		
		
		
		script.Parent.ParticleEmitter.Enabled = true
	
		
		
		
		local characterCframe = hit.Parent:GetPrimaryPartCFrame()
		
		local finalcframe = characterCframe
		
		local mpclone = MorphPath:Clone()
		mpclone.Parent = hit.Parent
		mpclone:SetPrimaryPartCFrame(finalcframe)
		
		-- torso creation
		
		local PrimaryPart = hit.Parent.Torso
		
		local characterTorsoCF = hit.Parent["Torso"].CFrame + Vector3.new(0, 0.2, 0)
		mpclone.Chest:SetPrimaryPartCFrame(characterTorsoCF)
		
		local Parts = mpclone.Chest:GetChildren()
