Inventory items are not saving upon return?

Hello!

I have a customized Backpack and Inventory for my game. When the player leaves the game and returns, the items inside the Backpack are there, but the items inside the Inventory are gone.

I assume I need to add additional lines to my DataStore script to save the Inventory items too? I added Line 4 and Line 21 to my DataStore, but its not quite working. Any advice? :)

Full DataStore script below for weapons/items:

--Setup the DataStore
local ds = game:GetService("DataStoreService"):GetDataStore("Tools");
local tools = game.ServerStorage.ToolStorage;  
local Inventory = game.StarterGui.HUDSystem.MainInventory.InventoryBox; -- ADDED LINE


--{[Check and Load]}
game.Players.PlayerAdded:connect(function(plr)

    --Retrieve the potential data
    local data = ds:GetAsync(plr.UserId);

    --Check if it exists
    if data then

        --If it does, loop and clone respective tools.
        for _,v in next,data do
            local tool = tools:FindFirstChild(v);
            if tool then
                tool:Clone().Parent = plr.Backpack;
                tool:Clone().Parent = plr.Inventory; -- ADDED LINE
            end
        end
    end
end)

--{[Collect and Save]}

game.Players.PlayerRemoving:connect(function(plr)

    --Make a table to hold all the data
    local toolList = {};

    --Iterate through the backpack and fill the table in

    for _,v in next,plr.Backpack:GetChildren() do
        --Make sure it's actually a tool

        if v:IsA("Tool") or v:IsA("HopperBin") then
            toolList[#toolList+1] = v.Name;
        end
    end
    --Save the table

    ds:SetAsync(plr.UserId,toolList);
end)
