I confirmed the 4 lines mentioned above are related to the problem of hiding items in the games menu. I was able to workaround the issue by removing the 4 lines in question from the mentioned file:
sudo cp /etc/xdg/menus/applications.menu /etc/xdg/menus/applications.menu.bak sudo sensible-editor /etc/xdg/menus/applications.menu
That caused lots of sub-menus to Games to appear, but at least hiding games started working.
