Dev Products give cash multiple times? [Solved]

At this point I think its a roblox bug, but when I spam click my buy button, or the roblox buy button, or even when I buy dev products multiple times without spamming I start to get extra cash. I'm using datastores to record purchases, I've tried to save it in a table and saving it in a seperate key but when I check if the purchase id is the same as the purchase id saved in the datastore, it doesnt print out the message its supposed to. I'm using numbervalues to store my cash (if that matters).

Server Script:

marketPlaceService.ProcessReceipt = function(recieptInfo)
    local playerId = recieptInfo.PlayerId
    local productId = recieptInfo.ProductId
    local purchaseId = recieptInfo.PurchaseId 

    local player = game.Players:GetPlayerByUserId(playerId)

    local purchaseKey = playerId .. '_' .. purchaseId

    local cashPurchaseData = purchaseLogDataStore:GetAsync(purchaseKey) 

    if not player then print('Product already bought') return Enum.ProductPurchaseDecision.NotProcessedYet end

    if cashPurchaseData then return Enum.ProductPurchaseDecision.PurchaseGranted end

    --[[for i, v in pairs(cashPurchaseData) do
        print(v)
        print(purchaseId)
        if v == purchaseId then
            print('Purchase already completed')
            return Enum.ProductPurchaseDecision.PurchaseGranted
        end
    end--]]

    if productId == oneHundredKProductId then
        player.Money.Value = player.Money.Value + 100000
    elseif productId == fiveHundredKProductId then
        player.Money.Value = player.Money.Value + 500000
    elseif productId == oneMProductId then
        player.Money.Value = player.Money.Value + 1000000
    elseif productId == fiveMProductId then
        player.Money.Value = player.Money.Value + 5000000
    elseif productId == tenMProductId then
        player.Money.Value = player.Money.Value + 10000000
    end

    playerStatsDataStore:SetAsync(playerId .. '_cash', player.Money.Value)


    --table.insert(cashPurchaseData, purchaseId)

    purchaseLogDataStore:SetAsync(purchaseKey, true)

    print('Purchase Finished') -- This prints less times than the amount of cash I'm supposed to get with each purchase

    return Enum.ProductPurchaseDecision.PurchaseGranted
end

Local Script:

marketPlaceService:PromptProductPurchase(player, selectedProduct)
