Why my datastore script dont working? It worked before i added a Bool Value saving.

That script worked before i added functuion to save bool value CompletedData. Please Help! Script:

local ds = game:GetService("DataStoreService"):GetDataStore("SaveData")
game.Players.PlayerAdded:Connect(function(plr)
	wait()
	local plrkey = "id_"..plr.UserId
	local save1 = plr.leaderstats.Stages
	local save2 = plr.leaderstats.Points
	local save3 = plr.leaderstats.Candy
	local save4 = plr.PlayerGui.QuestGui.CompletedData
	
	local GetSaved = ds:GetAsync(plrkey)
	if GetSaved then
		save1.Value = GetSaved[1]
		save2.Value = GetSaved[2]
		save3.Value = GetSaved[3]
		save4.Value = GetSaved[4]
	else
		local NumberForSaving = {save1.Value, save2.Value, save3.Value, save4.Value}
		ds:GetAsync(plrkey, NumberForSaving)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	ds:SetAsync("id_"..plr.UserId, {plr.leaderstats.Stages.Value, plr.leaderstats.Points.Value, plr.leaderstats.Candy.Value, plr.PlayerGui.QuestGui.CompletedData.Value})
end)
