I need help because when I click spin I get two "quirks", let's call them a quirk, the new quirk doesn't replace the old one, is there any method to make the previous quirk be replaced? If you need the script, I'll put what clones the quirk in the player's backpack.

local classes = game.ServerStorage.Classes

script.Parent.SpinEvent.OnServerEvent:Connect(function(plr, item, rarity)

local class = classes:FindFirstChild(item)

	if class then
		local cloned = class:Clone()
		cloned.Parent = plr.Backpack
	end
end)	

have the local script that make i get the class

local plr = game.Players.LocalPlayer
local cooldown = 3
local debounce = false
local defaultbackroundcolour = script.Parent.Parent.Result.BackgroundColor3

local backround = {
	
	{Rarity = "Common", Colour = Color3.fromRGB(255, 255, 255)},
	{Rarity = "Rare", Colour = Color3.fromRGB(0, 255, 0)},
	{Rarity = "Epic", Colour = Color3.fromRGB(126, 31, 185)},
	{Rarity = "Legendary", Colour = Color3.fromRGB(255, 255, 0)},
	
}

local item = {
	
	{Name = "OFA", Rarity = "Legendary"},
	{Name = "Ice", Rarity = "Rare"},
	{Name = "HHHC", Rarity = "Epic"},
	{Name = "Fire", Rarity = "Common"},
	
}

local lootTable1 = {
	
	{Item = item[1], Weight = 5},
	{Item = item[2], Weight = 37},
	{Item = item[3], Weight = 12},
	{Item = item[4], Weight = 0},
	
}

local function returnSumOfWeight(lootTable1)
	
	local sum = 0
	for i, entry in ipairs(lootTable1) do
		sum = sum + entry.Weight
	end
	return sum
	
end

local function getRandomItem(lootTable1)
	
	local randomNumber = math.random(returnSumOfWeight(lootTable1))

	for i, entry in ipairs(lootTable1) do
		if randomNumber <= entry.Weight then
			return entry.Item
		else
			randomNumber = randomNumber - entry.Weight
		end
		
	end
	
end

script.Parent.MouseButton1Click:Connect(function()
	if debounce == false then
		debounce = true
		
		for count = 1, 30 do
			local item = getRandomItem(lootTable1)
			script.Parent.Parent.Result.Text = item.Name
			wait(.05)
		end
		
		
		local item = getRandomItem(lootTable1)
		local name = item.Name
 		local rarity = item.Rarity

		script.Parent.SpinEvent:FireServer(name, rarity)
		script.Parent.Parent.Result.Text = name
		for i, v in ipairs(backround) do
			if v.Rarity == rarity then
				script.Parent.Parent.Result.BackgroundColor3 = v.Colour
			end
		end
		
		wait(cooldown)
		script.Parent.Parent.Result.Text = ""
		script.Parent.Parent.Result.BackgroundColor3 = defaultbackroundcolour
		debounce = false
	end
end)
