why does it say DataStore request was added to queue?

why does it say DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key =? I recently made a datastore script and I want to save 2 values but when I do 2 it says - DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key =. why does it do it and how do I fix it? If it is needed I will put the script. Please help script

game.Players.ChildAdded:connect(function(Player)

local Lead = Player.leaderstats

local Genorosity = Instance.new("IntValue",Lead)

Genorosity.Name = "Genorosity"

Genorosity.Value = 10

local cash = Instance.new("IntValue",Lead)

cash.Name = "Cash"

cash.Value = 4000

DataStore = game:GetService("DataStoreService"):GetDataStore("SaveCash")

local Key = Player.userId

local Data = DataStore:GetAsync(Key)

if Data then

cash.Value = Data

Genorosity.Value = data

end

end

end)

  

game.Players.ChildRemoved:connect(function(Player)

local Key = Player.userId

DataStore:SetAsync(Key,Player.leaderstats.Genorosity.Value)

DataStore:SetAsync(Key,Player.leaderstats.Cash.Value)

end)
