Why my PowerUp move in the workspace without me wanting it?

The 'PowerUp' should spawning at the UpperTorso position of the zombie but it will spawning on top of it and when a zombie touches him he goes up but I want that it remain her basic position, demonstration -->

• When a zombie touches him
• When he spawn

How to fix this?

PowerUp Script:

local RStorageService = game:GetService('ReplicatedStorage')
local LightingService = game:GetService('Lighting')
local SoundService = game:GetService('SoundService')


script.Parent.Touched:Connect(function(h)
	local player = game:GetService('Players'):GetPlayerFromCharacter(h.Parent)
	if player then
		--< My script
	end
end)

Rotation Script:

local c = 0
local a = 0

while wait() do
	if c < 200 then
		script.Parent.Orientation = script.Parent.Orientation + Vector3.new(0, 0.4, 0)
		c = c + 1
		a = 0
	elseif a < 50 then
		script.Parent.Orientation = script.Parent.Orientation + Vector3.new(0, -0.8, 0)
		a = a + .5
	else
		c = 0
	end
end

PowerUp spawning script:

local position = z.UpperTorso.Position
local PUp
	
if z.Zombie:FindFirstChild('PowerUp') ~= nil then
	PUp = z.Zombie.PowerUp.Value; z.Zombie.PowerUp:Destroy()
	
	local PoUp = RStorageService.PowerUp[PUp]:Clone()
	PoUp.Parent = workspace
	PoUp.Position = position
end
