Collision mixing system generating multiple new parts instead of just one

Hello, I have recently been creating a game with a system of mixing things by collision but this same system sometimes creates several new parts and for some reason they fade away and only leave one

Heres the code:

-- Require the cinnamorollmix module
local cinnamorollmix = require(game.ServerScriptService.cinnamorollmix)

-- Get the services needed
local TweenService = game:GetService("TweenService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local isMixing = false

-- Reference to the current part
local normalcinna = script.Parent

-- Function to handle the touch event
local function onTouch(otherPart)
    if isMixing then return end -- Prevent multiple simultaneous mixes

    for _, combo in ipairs(cinnamorollmix.mixCombinations) do
        if otherPart.Name == combo.Part2 then
            isMixing = true
            local newPartName = combo.Result
            local newPartTemplate = ReplicatedStorage:FindFirstChild("cinnamorollsmixes"):FindFirstChild(newPartName)

            if newPartTemplate then
                local newPart = newPartTemplate:Clone()
                newPart.Position = normalcinna.Position
                newPart.Parent = workspace

                -- Remove DragDetector if it exists
                local normalcinnaDragDetector = normalcinna:FindFirstChildOfClass("DragDetector")
                if normalcinnaDragDetector then
                    normalcinnaDragDetector:Destroy()
                end
                local otherPartDragDetector = otherPart:FindFirstChildOfClass("DragDetector")
                if otherPartDragDetector then
                    otherPartDragDetector:Destroy()
                end

                -- Add mixing effects
                local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Sine, Enum.EasingDirection.Out)
                local goal = {Transparency = 1}
                local tweenNormalcinna = TweenService:Create(normalcinna, tweenInfo, goal)
                local tweenOtherPart = TweenService:Create(otherPart, tweenInfo, goal)
                tweenNormalcinna:Play()
                tweenOtherPart:Play()

                -- Wait for the fade animation to complete and destroy parts
                tweenNormalcinna.Completed:Connect(function()
                    normalcinna:Destroy()
                end)
                tweenOtherPart.Completed:Connect(function()
                    otherPart:Destroy()
                end)

                -- Animation for the resulting part
                local goalNewPart = {Transparency = 0}
                local tweenNewPart = TweenService:Create(newPart, tweenInfo, goalNewPart)
                tweenNewPart:Play()

                -- Do not destroy the resulting part
                tweenNewPart.Completed:Connect(function()
                    isMixing = false -- Reset the mixing condition here
                end)
            else
                warn("Part not found in the cinnamorollsmixes folder")
                isMixing = false
            end

            break
        end
    end
end

-- Configure the mix event for "normalcinna"
if normalcinna then
    normalcinna.Touched:Connect(onTouch)
end
