Progress Bar glitching out sometimes

[MattyDevs]

Hello! Today, I wanted to create a progress bar UI for my math game. However, my client script sometimes behaves strangely.

Code:

ReplicatedStorage:WaitForChild("RemoteEvents"):WaitForChild("UpdatePlayerCountTeleport").OnClientEvent:Connect(function(TABLE)
    
    Functions.UpdatePlayerCount(TABLE)
    
    local ProgressFrame = player.PlayerGui:WaitForChild("MainGui"):WaitForChild("ProgressFrame")
    local PlayersFrame = ProgressFrame.Players
    
    local Colors = {
        Color3.new(0.313725, 1, 0.588235),
        Color3.new(1, 1, 0.294118),
        Color3.new(1, 0.52549, 0.184314),
        Color3.new(0.309804, 0.666667, 1),
        Color3.new(1, 0.32549, 0.337255),
        Color3.new(0.976471, 0.294118, 1),
    }
    
    for _, information in pairs(TABLE) do
        
        --[[
        
        information[1] = stage value
        information[2] = difficulty string
        information[3] = player
        
        ]]
        
        if not PlayersFrame:FindFirstChild(information[3].Name) then
            
            local content, isReady = game.Players:GetUserThumbnailAsync(tonumber(information[3].UserId), Enum.ThumbnailType.HeadShot, Enum.ThumbnailSize.Size420x420)
            
            local CLONE = script:WaitForChild("PlayerFrame"):Clone()
            CLONE.Name = information[3].Name
            CLONE.Frame.ImageLabel.Image = content
            CLONE.Frame.UIStroke.Color = Colors[math.random(1, #Colors)]
            CLONE.Parent = PlayersFrame
            CLONE:TweenPosition(UDim2.new(information[1] / 61 * 0.94, 0, -2.7, 0), Enum.EasingDirection.Out, Enum.EasingStyle.Linear, 0.08, false)
            
            if player.Name == information[3].Name then
                CLONE.Frame.Title.Visible = true
            end
            
        elseif PlayersFrame:FindFirstChild(information[3].Name) then
            PlayersFrame:FindFirstChild(information[3].Name):TweenPosition(UDim2.new(information[1] / 61 * 0.94, 0, -2.7, 0), Enum.EasingDirection.Out, Enum.EasingStyle.Sine, 0.1, false)
        end
        
        --Clean Up if someone left--
        
        for _, frame in pairs(PlayersFrame:GetChildren()) do
            if frame:IsA("Frame") then
                if not game:GetService("Players"):FindFirstChild(frame.Name) then
                    frame:Destroy()
                end    
            end
        end
    end
end)

Here are some screenshots showing the issue.

Any help is very appreciated!

Wait, so whats the issue you are experiencing?

As you can see there is a few clones of me in the screenshot, when there should be only one.

Try changing the line
if not PlayersFrame:FindFirstChild(information[3].Name) then
to
if PlayersFrame:FindFirstChild(information[3].Name) == nil then

Fixed the bug by adding spawn.task() and debounce.
