Did Filtering Enabled Break my DataStore?

Weird problem. My Backpack is only saving 7 items now. Anything purchased after that disappears after the player dies. The only thing I've changed recently is turning on Filtering Enabled. Did turning this on break my Data Store script? If so, how do I fix it?

Here's my script below:

--Setup the DataStore
    local ds = game:GetService("DataStoreService"):GetDataStore("REMOVED");
    local tools = game.ServerStorage.ToolStorage; --Specify all possible tools

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

    --Retrieve the potential data
    local data = false
    print("DataStoreBackSave1")
    plr.CharacterAdded:connect(function(char) -- this will run everytime the Player's Character has been added in workspace.
        if not data then
            data = ds:GetAsync(plr.UserId);
        end

        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;
                end
            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)
print("DataStoreBackSave2")
