Titan Skin Menu

Not sure if I have the right place, sorry if I don’t. On Titan Skin when using tiles as main menu and sub menu options, when I select submenu but press back to go back to sub menu it takes me back to main menu. Is the a setting to change for this ?, I have looked but can not find it and so thought it might have something to do with skin shortcuts. Please help or if not the correct forum please redirect me. Thanks Mike
