For some reason, my script is saving the wrong items, Help?

I have a script that saves the tools and the leaderstats. It works, but there's a really weird problem. If i join my game, get different tools, leave and rejoin the game, some of the tools loaded are replaced with Healing Potions, and sometimes it has additional healing potions. For example:

Joined game

Gets Sword, Trowel and a Superball

Leaves game (When i leave the items that i just got are saved)

Joins game

**Loads ** up for me a Healing potion, Trowel, Healing potion

What is causing this weird problem? Script:

local DataStore = game:GetService("DataStoreService"):GetDataStore("RoaHSave")

game.Players.PlayerAdded:connect(function(newPlayer)

    local Backpack = newPlayer:WaitForChild("Backpack")
    newPlayer:WaitForChild("StarterGear")

    local key = "user-"..newPlayer.userId

    local savedData = DataStore:GetAsync(key)


    --If player has data saved, load data. If not, save current data.
    if savedData then
