Hi!
This is not actually an error, but the common user practice will generate it:
Very often the Homepage is replaced with a Home icon to look better in the Navigation.
The Breadcrumbs element allows displaying the icon or text. If icon is selected, it will default to the Menu name in Schema output, but it is an icon there too. So the Schema is invalid.
I think something should be done here, because I imagine many users are using Icons in menus, and are not aware of the fact that it breaks the Schema.
(If Home is changed to text instead of an icon, then it displays correctly).
So to keep Icons both in Navigation and breadcrumbs, I guess the Breadcrumb element should have a field to enter the Home name if Icon is selected.
Thanks!
