I'm using Ubuntu 14.04, with LXDE (Lubuntu).

The menu displayed by LXMED is not the same as what I see on the actual menu.

There are some unwanted items on my actual menu that I want to delete, but I cannot see them in LXMED.

Some items that appear in LXMED are not on the actual menu (or are under different categories). The bold items in LXMED does not correspond to whether an item appears in the actual menu or not.

Perhaps the software is outdated and there is a new scheme for menu structure?
