The `off` is normal. I used them to fill the remaining slots of the menu,
so I can always keep correctly the menu's numbers 8, 9, and 0,
when there are not enough maps to fill the menu.
I need to do this because I am using the new menu's style and I replaced the default menu buttons
`exit`, `more` and `back` by my own implementation, so I can add only the menu's entries displayed
to the user. Therefore you server can build a menu with 10000 maps with no lags, because the menu
will only load 8 entries, instead of 10000 when build it.
