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)
				
wait(1) -
				
debounce = false -- I've added a debounce before this.
