Tool saver gave more too many of 1 tool is there a way to fix it?

So when you die it gives you the tool back if you have it and if it's in the toolFolder it may give you double amount of the tool(s) you own

script:

local dss = game:GetService("DataStoreService")
local toolsDS = dss:GetDataStore("ToolsData")
local toolsFolder = game.ReplicatedStorage.Items

game.Players.PlayerAdded:Connect(function(plr)
    local toolsSaved
    local s,e = pcall(function() 
        toolsSaved = toolsDS:GetAsync(plr.UserId .. "-tools") or {}
    end)
    if s then
        plr.CharacterAdded:Connect(function(player) -- this gives the tools to the player once they have respawned, after they died, etc and also gives too many of 1 tool
            giveTools(plr, toolsSaved)
        end)
        plr.CharacterRemoving:Connect(function(char)
            char.Humanoid:UnequipTools()
        end)
    else
        warn(e)
    end
end)


game.Players.PlayerRemoving:Connect(function(plr)
    local toolsOwned = {}
    for i, toolInBackpack in pairs(plr.Backpack:GetChildren()) do   
        table.insert(toolsOwned, toolInBackpack.Name)
    end
    local success, errormsg = pcall(function()      
        toolsDS:SetAsync(plr.UserId .. "-tools", toolsOwned)
    end)
    if errormsg then warn(errormsg) end
end)

function giveTools(player, tools) -- just a function so you dont have to write it multiple times, not needed but cleans up code for later
    if player and player:IsA("Player") then -- checks if the given player is a "Player"
        for i,toolSaved in pairs(tools) do
            if toolsFolder:FindFirstChild(toolSaved) then       
                toolsFolder[toolSaved]:Clone().Parent = player.Backpack
                toolsFolder[toolSaved]:Clone().Parent = player.StarterGear 
            end
        end
    end 
end
