my data store not saving my data when leaving the game and entering it?

I recently made a datastore where i store 2 values in Strength and cash

Cash an strength perfectly show up when playing but when i close down the game and open it again it goes back to 0

local DataStore = game:GetService("DataStoreService")
local ds1 = DataStore:GetDataStore("CashDataStore")
local ds2 = DataStore:GetDataStore("StrengthDataStore")

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

    local leader = Instance.new("Folder",player)
    leader.Name = "leaderstats"

    local cash = Instance.new("IntValue",leader)
    cash.Name = "cash"

    local strength = Instance.new("IntValue",leader)
    strength.Name = "strength"

    strength.Value = ds2:GetAsync(player.UserId) or 0
    ds2:SetAsync(player.UserId, strength.Value)

    cash.Value = ds1:GetAsync(player.UserId) or 0
    ds1:SetAsync(player.UserId, cash.Value)

    cash.Changed:connect(function()
    ds1:SetAsync(player.UserId, cash.Value)
    end)

    strength.Changed:connect(function()
    ds2:SetAsync(player.UserId, strength.Value)
    end)
end)

game.Players.PlayerRemoving:Connect(function(player)
    ds1:SetAsync(player.UserId, player.leaderstats.cash.Value)
    ds2:SetAsync(player.UserId, player.leaderstats.strength.Value)
end)
