I have a script which im using to spawn Collectables in the game im working on, but for some reason the part is getting removed from the table even though every time it should be getting removed from the table it should also get deleted.

function Collectables:Spawn(Position)
    local CurrencyPart = self.Object:Clone()
    
    CurrencyPart.Parent = CollectableFolder
    CurrencyPart.Anchored = false
    CurrencyPart.CFrame = CFrame.new(Position)
    
    table.insert(self.Parts,CurrencyPart)
    
    local BP = Instance.new('BodyPosition',CurrencyPart)
    BP.Name = 'BP'
    BP.MaxForce = Vector3.zero
    BP.P = 100
    BP.D = 10
    
    delay(15,function()
        CurrencyPart:Destroy()
        table.remove(self.Parts,table.find(self.Parts,CurrencyPart))
    end)
end

function Collectables:ConnectHeart()
    self.Heart = self.Heart and self.Heart:Disconnect() or RunService.Heartbeat:Connect(function()
        for _,Player in pairs(game:GetService('Players'):GetPlayers()) do
            local CharacterPosition = Player.Character and Player.Character:FindFirstChild('HumanoidRootPart').Position
            for _,Part in pairs(self.Parts) do
                if Player.Character and (CharacterPosition - Part.Position).Magnitude <= 2 then
                    Part:Destroy()
                    table.remove(self.Parts,table.find(self.Parts,Part))
                    Sounds.PlaySound('rbxassetid://17295477114',.5,CharacterPosition)
                end
            end
        end
    end)
end

So if I understood correctly, your collectables arent being destroyed but they stop existing in self.Parts? Is the delay 15 and player being close to the part the only places where they should get removed from the table or are there more?
