Data Store Not Saving Data, Folders with IntValues?

I made a Folder that has another folder that has IntValues. When I go in-game and change one of my values and I leave the game it will not save the value! Please help!

local Data = game:GetService("DataStoreService"):GetDataStore("Stats")

game.Players.PlayerAdded:connect(function(player)
	local Key = "Player-"..player.userId
	local PlayerFolder = Instance.new("Folder", player)
	PlayerFolder.Name = "PlayerFolder"
	local StatFolder = Instance.new("Folder", PlayerFolder)
	StatFolder.Name = "Stats"
	local Strength = Instance.new("IntValue", StatFolder)
	Strength.Name = "Strength"
	local Defense = Instance.new("IntValue", StatFolder)
	Defense.Name = "Defense"
	local Sword = Instance.new("IntValue", StatFolder)
	Sword.Name = "Sword"
	
	local Data1 = Data:GetAsync(Key)
	
	if Data1 then
		PlayerFolder = Data1[1]
		StatFolder = Data1[2]
		Strength.Value = Data1[3]
		Defense.Value = Data1[4]
		Sword.Value = Data1[5]
	else
		local ThingsToSave = {PlayerFolder,StatFolder,Strength.Value,Defense.Value,Sword.Value}
		local GiveData = Data:GetAsync(ThingsToSave,Key)
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local Key = "Player-"..player.userId
	local Save = {player.PlayerFolder.Stats.Sword.Value,player.PlayerFolder.Stats.Defense.Value,player.PlayerFolder.Stats.Strength.Value}
	local SaveData = Data:SetAsync(Save, Key)
end)
