DataStore - Try sending fewer requests?

Yo, so I've made a bool value inside leaderstats script that I copied from a tutorial. The Bool Value says whether or not a player owns a vehicle. I have two values, Money and the Vehicle. The vehicle saves, however the money does not. Any help is appreciated.

Error: DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key = Money-226030996

local currencyName = "Money"
local Car1Owned = "Car1Owned"
local DataStore = game:GetService("DataStoreService"):GetDataStore("TestDataStore")

game.Players.PlayerAdded:Connect(function(player)

    local folder = Instance.new("Folder")
    folder.Name = "leaderstats" 
    folder.Parent = player

    local currency = Instance.new("IntValue")
    currency.Name = currencyName
    currency.Parent = folder

    local Owned = Instance.new("BoolValue")
    Owned.Name = Car1Owned
    Owned.Parent = folder

    local ID = currencyName.."-"..player.UserId


    local savedData = nil

    pcall(function()
        savedData = DataStore:GetAsync(ID)
    end)

    if savedData ~= nil then
        Owned.Value = savedData
        currency.Value = savedData
        print("Data loaded")
    else
        -- new player
        currency.Value = 1000
        print("New player to the game")
    end

end)

game.Players.PlayerRemoving:Connect(function(player)
    local ID = currencyName.."-"..player.UserId
    DataStore:SetAsync(ID,player.leaderstats[currencyName].Value)
    DataStore:SetAsync(ID,player.leaderstats[Car1Owned].Value)
end)
