Static Page as home page get full_width

Full width is intended to have no sidebars–it’s full width. If you want sidebars, use the default page template. Or you can build a custom template based on page.php. A custom template will allow you to create a custom sidebar or build custom widget areas on the page.

I know that ??
I discover the problem. In some way, I change the model in page atributes to full width, coincided that I change this same page to be my home page. This way I mixed the whole thing.
