home menu button error

hi i was unpublish the home menu button , and i make the home menu button another category.
after i try to change it to home again i get this error

''Save failed with the following error: The home menu item must be a component.''

i change the menu item type as future articles and then it was possible to make the home button as ''home'' again

but the front page is not like before so i try to change again as menu item alias but i still get that error

any help please.
the website is liocollection.net

It look ok. Generally if you changed menu item parent menu that could case loss of data about menu assignment.
