(How too) When equipping a tool and the local limit has already been met, the tool you tried to equip replaces the last tool in the backpack

Here is what I have setup currently

local par = script.Parent
local remote = par.RemoteEvent
local tools = par.Tools
local limit = 2

local function DuplicatesExist(arr: {any}): {any}?
	if not arr then
		return
	end

	local hash = {}
	local dups = {}

	for _,v in ipairs(arr) do
		if hash[v] then
			if not dups[v] then
				table.insert(dups, v)
			end
		else
			hash[v] = true
		end
	end
	return dups
end

local function Check(player: Player)
	if not player then
		return
	end

	local backpack = player.Backpack
	local arr = backpack:GetChildren()

	local check = DuplicatesExist(arr)

	for i,v in ipairs(check) do
		arr[v]:Destroy()
	end
end

remote.OnServerEvent:Connect(function(plr, info)
	if #plr.Backpack:GetChildren() < limit then
		if info == "Tool1" then
			Check(plr)

			local tool = tools["Barret M82"]:Clone()
			tool.Parent = plr.Backpack
		elseif info == "Tool2" then
			Check(plr)

			local tool = tools["Glock 19"]:Clone()
			tool.Parent = plr.Backpack
		elseif info == "Tool3" then
			Check(plr)

			local tool = tools.HK416:Clone()
			tool.Parent = plr.Backpack
		end
	end
end)
