Id Loader Script - Multiple Values in a Leaderstats format?

My Question is relevant to this code:

local DSService = game:GetService('DataStoreService'):GetDataStore('JerryYoutube-Spells-Place-5')
-- Name of Data Store Must be random, long or obscure to make sure that it is not taken as an ID for another Store of Data
game.Players.PlayerAdded:connect(function(plr)
	local loaded = script.Parent.loaded
	loaded.Value = 0
	-- Def Vars
	local IdPlr = "id-"..plr.userId
	local ls = Instance.new("IntValue", plr)
	-- Ls = LeaderStats
	local ls2 = Instance.new("IntValue",plr)
	local sv = Instance.new("IntValue")
	-- Save Value
	ls.Name = 'ls'
	-- if u change ^ u must change them all
	ls2.Name = 'ls2'
	sv.Parent = ls
	sv.Name = 'Spell_Count'
	-- U can change ^ if u want - but u must change all the other references as well
	local sv2 = Instance.new("IntValue")
	sv2.Parent = ls2
	sv2.Name = "Rank"
	
	
	-- Get Async
	local RVFS = DSService:GetAsync(IdPlr)
	-- Return Values From Saved (Data)
	if RVFS then
		sv.Value = RVFS[1]
		sv2.Value = RVFS[1]
	else
		local NFS = {sv.Value}
		local NFS2 = {sv2.Value}
		-- 	Numbers for Saving (Int-Type) operand + , num(spells)
		DSService:SetAsync(IdPlr,NFS)
		DSService:SetAsync(IdPlr,NFS2)
	end
	loaded.Value = 1
	Admin_Check(plr)
end)

game.Players.PlayerRemoving:connect(function(plr)
	local IdPlr = "id-"..plr.userId
	-- Since it has the identifier "Local" it cannot be referenced in between functions; because of OOP
	local ST = {plr.ls.Spell_Count.Value}
	local ST2 = {plr.ls2.Rank.Value}
	DSService:SetAsync(IdPlr,ST)
	DSService:SetAsync(IdPlr,ST2)
end)

function Admin_Check(plr)
	-- Function Deals with the connection of Clients to the Server and helps the main function check if the User is an Admin
	-- Takes an Input of player
	-- GSP : Get Spell count of Player
	print(game.Workspace.Scripts.Storage.IdLoader.loaded.Value)
	local DSService = game:GetService('DataStoreService'):GetDataStore('JerryYoutube-Spells-Place-5')
	local GSP = game.StarterGui.GSP
	local Rank = game.StarterGui.RankControl
	GSP.Enabled = false -- Changes the GetSpellCount of Player Screen Gui to not show
	if game.Workspace.Scripts.Storage.IdLoader.loaded.Value == 1 then
		print("Loaded TRUE")
		end
	if plr.UserId == 92471106 then
		print("Owner JerryYoutube is Online!")
		print(plr.ls.Spell_Count.Value)
		print(plr.ls2.Rank.Value)
		GSP.Enabled = true -- Changes the GetSpellCount of Player Screen Gui to show
		Rank.Enabled = true
	elseif plr.UserId == 63044886 then
		print("Admin tjminecraft1 is Online!")
		GSP.Enabled = true
		Rank.Enabled = true
	else 
		GSP.Enabled = false
		Rank.Enabled = false
	end
	GetRank(plr,plr.ls2.Rank.Value)
	
end

function GetRank(plr,rank)
	print(rank)
	print(plr)
	
end

And I would like to know why the values for both no longer save in-game. As I tested this code with Just 1 leaderstats and 1 value in that leaderstats (ls and sv) and It worked. i would Like to know why it doesn't work and please can someone patch it up so that I can store 2 values in the one leaderstats table and save both when the player (plr) leaves. And loads their data (plr) when they return.

Thanks for any help you can give.
