My datastore values are being replaced and they don’t get added

local DataStoreService = game:GetService("DataStoreService")

local playerDataStore = DataStoreService:GetDataStore("PlayerDataStore")
local sellOrdersDataStore = DataStoreService:GetDataStore("SellOrders")

local function saveSellOrder(player, sellOrderRobotName, sellOrderPrice)
	local key = "R_" .. sellOrderRobotName
	
	local success, sellOrder = pcall(function()			
		sellOrdersDataStore:UpdateAsync(key, function(sellOrders)
			print(sellOrders)
			if sellOrders == nil then
				sellOrders = {}
			end
			
			table.insert(sellOrders, {
				SellOrderPlayer = player.UserId,
				SellOrderPrice = sellOrderPrice
			})
			
			return sellOrders
		end)
	end)
	
	local success, currentSellOrder = pcall(function()
		return sellOrdersDataStore:GetAsync(key)
	end)

	if success then
		print(currentSellOrder)
	end
end

workspace.Robot1Part.ClickDetector.MouseClick:Connect(function(player)
	saveSellOrder(player, workspace.Robot1Part.Name, math.random(10, 20))
end)

workspace.Robot2Part.ClickDetector.MouseClick:Connect(function(player)
	saveSellOrder(player, workspace.Robot2Part.Name, math.random(50, 100))
end)

workspace.Robot3Part.ClickDetector.MouseClick:Connect(function(player)
	saveSellOrder(player, workspace.Robot3Part.Name, math.random(200, 500))
end)

When I print the key the first time it will print 2 values
When I click another part it will still only print 2 different values

Try using SaveAsync() but I’m not sure it will work.
