My ToolSave System saves my tools but when deleted it's still there?

When I buy a weapon from my gui shop, it gives it to me. But when I delete all the tools in my inventory, and then get out of the game, it still shows them, so I deleted it again and bought some more weapons, I left. And it actually added onto it. How can you fix this glitch?

			local clone = tool:Clone()
			clone.Parent = player.Backpack
		else
			print(list[i] .. " not found")
