Why does my MouseButton1Click function act like it's being pressed twice ?

I don't know the actual issue; this is my first time I've got this issue and I've been working with MouseButton functions quite alot. I click it for the first time, it functions as if it's being pressed twice and then I click it again, 4 times, again, 8 times and so on.

for i, v in pairs(petsel) do
    petsel[i].MouseButton1Click:Connect(function() 
        CircleClick(petsel[i], Mouse.X, Mouse.Y)
        local buttonclick = petsel[i]
        local PetN = buttonclick.PetN.Text
        local Opt = script.Parent.Frame.Page.Pets.Opt
        Opt.PetImage.Image = "rbxassetid://" ..(require(game.ReplicatedStorage.PetDesc).basketdata[PetN][1]).. ""
        Opt:TweenPosition(UDim2.new(1.1, 0, 0,0), "Out", "Sine", 0.5)
        Opt.Spawn.MouseButton1Click:connect(function()
--          local clicks = 0
--          local clicks = clicks + 1
--          if clicks == 1 then
                Opt.Spawn.Selectable = false
                CircleClick(Opt.Spawn, Mouse.X, Mouse.Y)

                ReplicatedStorage.Events.SpawnPet:FireServer(PetN)

                Opt:TweenPosition(UDim2.new(0.75, 0, 0,0), "Out", "Sine", 0.5)
                Opt.Spawn.Selectable = true
                local clone = Player.PlayerGui.PetUI.Examples.PetSelec.ImageButton:Clone()
                clone.PetPic.Image = "rbxassetid://".. require(game.ReplicatedStorage.PetDesc).basketdata[PetN][1] ..""
                clone.ImageColor3 = Color3.new(require(game.ReplicatedStorage.PetDesc).basketdata[PetN][3],require(game.ReplicatedStorage.PetDesc).basketdata[PetN][4],require(game.ReplicatedStorage.PetDesc).basketdata[PetN][5])
                clone.PetName.Text = PetN
                clone.Visible = true
                clone.Name = PetN
                print(clone.Name)
                clone.Parent = Player.PlayerGui.PetUI.SideGUI.SelectionPets
                local way = Player.PlayerGui.PetUI.SideGUI.SelectionPets:WaitForChild(clone.Name)
--              clicks = 0
--          end
        end)
        Opt.removep.MouseButton1Click:connect(function()
            local clicks = 0
            local clicks = clicks + 1
            if clicks == 1 then
                Opt.Spawn.Selectable = false
                Opt.removep.Selectable = false
                CircleClick(Opt.removep, Mouse.X, Mouse.Y)
                ReplicatedStorage.Events.RemovePet:FireServer(PetN)
                Opt:TweenPosition(UDim2.new(0.75, 0, 0,0), "Out", "Sine", 0.5)
                Opt.Spawn.Selectable = true
                Opt.removep.Selectable = true
                local selectionpets = Player:WaitForChild("PlayerGui"):WaitForChild("PetUI"):WaitForChild("SideGUI").SelectionPets
                if selectionpets:FindFirstChild(PetN) then
                    selectionpets[PetN]:Destroy()
                end
                clicks = 0
            end
        end)
    end)
