Data cannot be found?

Whenever I try to save my data, it’s not saving. I’ve used DatastoreEditor to edit my data, and it’s saying that I don’t have it. It’s just not loading and I don’t know what’s wrong.

--# DataHandler.Lua will make sure we can load data of owner boomboxes, and our music value.

local V1PER = require(game.ReplicatedStorage.V1PER)

local OwnedBoomboxes = game:GetService("DataStoreService"):GetDataStore("OwnedBoomboxes")

game.Players.PlayerAdded:Connect(function(Player)
	local Data = V1PER.DataStoreResource.Builder.BuildNewLeaderstats({
		{
			Name = "Music",
			TypeValue = "Int",
			Default = 0
		}	
	}, Player)
	
	V1PER.DataStoreResource.DataStore.LoadData(Player, Data)
	
	local retrievedData
	
	local found, errorOccured = pcall(function()
		retrievedData = OwnedBoomboxes:GetAsync(Player.UserId.. "$")
	end)
	
	if found then
		if retrievedData then
			warn("Player has existing data")
			if type(retrievedData) == "table" then
				warn("List of owned boomboxes: true")
				local BoomboxesOwned = script:WaitForChild("BoomboxesOwned"):Clone()
				BoomboxesOwned.Parent = Player
				for name, owned in pairs(retrievedData) do
					if require(BoomboxesOwned)[name] then
						require(BoomboxesOwned)[name] = owned
						game.ReplicatedStorage.Boomboxes:WaitForChild(name):Clone().Parent = Player.Backpack
					end
				end
			else
				error("Cannot be an instance type that is not a table!")
			end
		else
			warn("Player has no data!")
			local BoomboxesOwned = script:WaitForChild("BoomboxesOwned"):Clone()
			BoomboxesOwned.Parent = Player
		end
	else
		error(errorOccured)
	end
end)

game.Players.PlayerRemoving:Connect(function(Player)
	V1PER.DataStoreResource.DataStore.SaveData(Player)
	local list = require(Player:WaitForChild("BoomboxesOwned"))
	
	local success, err = pcall(function()
		OwnedBoomboxes:SetAsync(Player.UserId.. "$", list)
	end)
	
	if success then
		for boombox, owned in pairs(list) do
			warn("Name; ".. tostring(boombox))
			warn("Owned; ".. tostring(owned))
		end
		warn("Saved player boomboxes")
	else
		error(err)
	end
end)
