F.A.Q: Breadcrumb is not hiding?

You probably are switching ON/OFF the option breadcrumb and still seeing a "breadcrumb" on your page, that's because breadcrumb is placed in two locations, as a stand alone part and as subtitle in the hero.

Hero options are located in two different places, in the Appearance > Customizer > Utility > Hero, where it can be enabled or disabled for all pages at once, also there are options in each post or page where you can choose if you want to inherit the values from the Customizer or set them custom.

So if you want to hide the hero for a single page, edit that page with regular WordPress editor and go to Page Settings > Hero > Visibility.
