Donation board saying the player donated 5 robux but there isn't a 5 robux donation in the board?

On spawn, most of the time, the donation board thinks that the player donated 5 robux even though there is no "5 Robux" donation button and the player didn't donate anything? What? What is happening here? Also sometimes the leaderboard would say the player didn't donate anything if didn't donate but when it updates it says the player donated 5 robux, but anyways here are the scripts:

The leaderstats (or hiddenstats) script: (ServerScriptService)

local DataStoreService = game:GetService("DataStoreService")
local DonationDataStore = DataStoreService:GetDataStore("Donation")

game.Players.PlayerAdded:Connect(function(player)
    local hiddenstats = Instance.new("Folder") 
    hiddenstats.Name = "hiddenstats" 
    hiddenstats.Parent = player

    local Donation = Instance.new("IntValue", hiddenstats)
    Donation.Name = "Donation"
    Donation.Value = DonationDataStore:GetAsync(player.UserId) or 0

end)

game.Players.PlayerRemoving:Connect(function(Player)
    DonationDataStore:SetAsync(Player.UserId, Player.hiddenstats.Donation.Value)
end)

The donation board script: (StarterGui)

local lbData = game:GetService("DataStoreService"):GetOrderedDataStore("Board")

function AddCommas(num)
    return tostring(math.floor(num)):reverse():gsub("(%d%d%d)","%1,"):gsub(",(%-?)$","%1"):reverse()
end

function Update()
    local frames = script.Parent.ScrollingFrame:GetChildren()
    for v,v in pairs(frames) do
        if v:IsA("Frame") then
            v:Destroy()
        end
    end
    for _,plr in next, game:GetService("Players"):GetPlayers() do
        pcall(function()
            lbData:UpdateAsync(plr.UserId, function() return plr:FindFirstChild("hiddenstats"):WaitForChild("Donation").Value end) 
        end)
    end

    local data = lbData:GetSortedAsync(false,10)
    local page = data:GetCurrentPage()

    for rank, info in next, page do
        local frame = script.Parent.Sample:Clone()
        frame.Visible = true
        local plrName = game:GetService("Players"):GetNameFromUserIdAsync(info.key)     
        frame:WaitForChild("Place").Text = "#"..rank
        if rank == 1 then
            print("gold")
            frame.BackgroundColor3 = Color3.new(0.941176, 0.737255, 0)
        elseif rank == 2 then
            print("silver")
            frame.BackgroundColor3 = Color3.new(0.784314, 0.784314, 0.784314)
        elseif rank == 3 then
            print("bronze")
            frame.BackgroundColor3 = Color3.new(0.764706, 0.560784, 0.313725)
        else
            print("white")
            frame.BackgroundColor3 = Color3.new(1, 1, 1)
        end
        frame.Username.Text = plrName
        frame.Amount.Text = AddCommas(info.value)
        frame.Visible = true

For anyone thinking that there is some code that adds 5 donation points, I tried my hardest to find it and there are NO signs of it.
