Hi Tuelo,
Could you please let me know the Menu item type that you are using for Home menu item ? Gantry5 custom page or category blog layout ?
By default, The home menu item assigned to Quix Home page, you can change the menu item type to category blog or single article to show the Joomla article(s)
Note: You can provide a screenshot the result you want so I can help about layout configuration.
Thank you
