Why is my DataStore only saving one value from the dictionary?

I am working on a datastore, and I it only saves one value, I need help figuring out why, I am not posting all the code, but this is the main part of it, I am using a dictionary for saving the values

Code:

function module.load(plr, stats, name)
	
	local dataService = game:GetService("DataStoreService"):GetDataStore(name)
	local leaderstats = plr:WaitForChild("leaderstats")
	
	local key = plr.UserId.. "-key"
	
	local savedValues = dataService:GetAsync(key)
	
	if savedValues then
		for index, value in pairs(savedValues) do
			leaderstats[tostring(index)].Value = value
		end
	else
		for index,value in pairs(stats) do
			local values = {}
			values[tostring(index)] = leaderstats[tostring(index)].Value
			dataService:SetAsync(key, values)
		end
	end
			
end

Here is the bit of code that I believe is messing up:

for index,value in pairs(stats) do
	local values = {}
	values[tostring(index)] = leaderstats[tostring(index)].Value
	dataService:SetAsync(key, values)
end

Heres a warning that is appearing:
