Data Storage won't save?

I don't really know how to script data storage, so I watched a video about it and came up with this. The script is almost identical to the one in the video excepting the stringvalues. Everyone commenting the video claim it works but for me it doesn't save. I have API enabled in the game I'm scripting it. Is it because of the stringvalues?

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

game.Players.PlayerAdded:Connect(function(plr)
	local Folder = Instance.new("Folder",game.ServerStorage:FindFirstChild("CurrentLoadout"))
	Folder.Name = plr.Name
	local Primary = Instance.new("StringValue",Folder)
	Primary.Name = "Primary"
	local Secondary = Instance.new("StringValue",Folder)
	Secondary.Name = "Secondary"
	local SavedItems = Data:GetAsync(plr.userId)
	if SavedItems then
		Primary.Value = SavedItems.Primary or "None"
		print(Primary.Value)
		Secondary.Value = SavedItems.Secondary or "None"
		print(Secondary.Value)
	else
		Primary.Value = "None"
		Secondary.Value = "None"
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	
	local Saving = {["Primary"] = game.ServerStorage.CurrentLoadout:FindFirstChild(plr.Name).Primary.Value;
		  			["Secondary"] = game.ServerStorage.CurrentLoadout:FindFirstChild(plr.Name).Secondary.Value
	}
	Data:SetAsync(plr.userID,Saving)
	
end)
