How do I save multiple things in a OrderedDataStore?

So I have been trying to get this ordered datastore to save 3 different player datas. I have tried saving them separately, but I get the orange error that says theres too many inputs for the key. It said it didn't allow Dictionaries either. Then a JSON encoded it but it doesn't accept strings. I need help. I Know that Ordered datastores only accept numbers. Heres the code:

local DSS = game:GetService("DataStoreService")
local DS = DSS:GetOrderedDataStore('plrData')

game.Players.PlayerAdded:Connect(function(plr)
	local data
	local key = plr.Name
	pcall(function()
		data = DS:GetAsync(key)
	end)
	local folder = Instance.new("Folder")
	folder.Parent = plr
	folder.Name = 'leaderstats'
	local Steps = Instance.new("IntValue")
	Steps.Parent = folder
	Steps.Name = 'Steps'
	local Total = Instance.new("IntValue")
	Total.Parent = folder
	Total.Name = 'TotalSteps'
	local Wins = Instance.new("IntValue")
	Wins.Parent = folder
	Wins.Name = 'RaceWins'
	if data then
		Steps.Value = data.idk['Steps']
		Total.Value = data.idk['Total']
		Wins.Value = data.idk['Wins']
	else
		Steps.Value = 0
		Total.Value = 0
		Wins.Value = 0
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local key = plr.Name
	local idk = {}
	idk['Steps'] = plr.leaderstats.Steps.Value
	idk['Total'] = plr.leaderstats.TotalSteps.Value
	idk['Wins'] = plr.leaderstats.RaceWins.Value
	DS:SetAsync(key, idk)
end)

reminder: no rude or toxic stuff about the simulator part.
