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
