'games' Submenu Empty

I have installed xmoto and lgeneral. After that sumbenu games in my system menu is empty - I can enter it but there are no games. Other menus are OK. When I run Kmenuedit there are proper entries in submenu 'Games'.

Is it possoble to 'rebuild' system menu?

If you make a change in the Kmenu editor it should 'Update System Configuration'. See if that will help.

I've clicked 'save' in Kmenuedt and there was system config. update, but still nothing. 'games' submenu is empty.

and, what is interesting, in 'search' in system menu, when i type for example xmoto, I get proper result
