Why does getting data from DataStores return this hexadecimal thing?

What I'm trying to do is to make a data system that makes player files in Replicated Storage with the data so other scripts can access the data for the player.

Code for getting data (no problem with other stuff for now):

local function dataStoreRetry(dataStoreFunction)
		local tryCount = 0
		local success = false
		local data = nil
		
		repeat
			tryCount = tryCount + 1
			
			success = pcall(function()
				data = dataStoreFunction()
			end)
			
			if not success then
				error("There was an error. Data may not save.")
			end
		until tryCount == dataRetries or success
		
		return success, data
	end
	
	local function getPlayerData(player)
		return dataStoreRetry(function()
			return playerData:GetAsync(player.UserId)
		end)
	end

Code for setting up the player file:

local function setupPlayerFile(player)
		print("Setting up player file...")
		
		local success,data = getPlayerData(player)
		print(success,data)
		
		--                                          All weapons:                Equipped weapons:
		--Data table structure: {Kills,Deaths,[[Weapon,Attachments] ... ],[[Primary,Attachments],[Secondary,Attachments],[Melee]}
		
		if success then
			if data then
				local plFile = Instance.new("Folder")
				plFile.Name = player.Name .. " plFile"
				plFile.Parent = game.ReplicatedStorage["Player Files"]
				
				local killCount = Instance.new("IntValue")
				killCount.Name = "Kills"
				killCount.Parent = plFile
				killCount.Value = data[1]
				
				local deathCount = Instance.new("IntValue")
				deathCount.Name = "Deaths"
				deathCount.Parent = plFile
				deathCount.Value = data[2]
				
				local kdrCount = Instance.new("NumberValue")
				kdrCount.Name = "KDR"
				kdrCount.Value = math.ceil(killCount.Value/deathCount.Value)
				
				local primaryValue = Instance.new("StringValue")
				primaryValue.Parent = plFile
				primaryValue.Name = "PrimaryWeapon"
				primaryValue.Value = data[4][1][1]
		
				local secondaryValue = Instance.new("StringValue")
				secondaryValue.Name = "SecondaryWeapon"
				secondaryValue.Parent = plFile
				secondaryValue.Value = data[4][2][1]
		
				local meleeValue = Instance.new("StringValue")
				meleeValue.Name = "MeleeWeapon"
				meleeValue.Parent = plFile
				meleeValue.Value = data[4][3]
		
				print("Setup player file.")
			end
			
			if not data then
				local plFile = Instance.new("Folder")
				plFile.Name = player.Name .. " plFile"
				plFile.Parent = game.ReplicatedStorage["Player Files"]
				
				local primaryValue = Instance.new("StringValue")
				primaryValue.Parent = plFile
				primaryValue.Name = "PrimaryWeapon"
				primaryValue.Value = "Starter AR"
		
				local secondaryValue = Instance.new("StringValue")
				secondaryValue.Name = "SecondaryWeapon"
				secondaryValue.Parent = plFile
				secondaryValue.Value = "Simple Pistol"
		
				local meleeValue = Instance.new("StringValue")
				meleeValue.Name = "MeleeWeapon"
				meleeValue.Parent = plFile
				meleeValue.Value = "Knife"
		
				print("Setup player file.")
			end
		else
			warn("Data was setup unsuccessfully.")
		end		
	end

(its not done yet lol)

However, when I run the module script, this happens:

Setting up player file...
