So, I think I found the right file, and based on this I’m not sure why I have a p element for the site title on the frontpage. Maybe I missed some settings?
// Build our site title.
$site_title = apply_filters( 'generate_site_title_output', sprintf(
'<%1$s class="main-title" itemprop="headline">
<a href="%2$s" rel="home">
%3$s
</a>
</%1$s>',
( is_front_page() && is_home() ) ? 'h1' : 'p',
esc_url( apply_filters( 'generate_site_title_href', home_url( '/' ) ) ),
get_bloginfo( 'name' )
) );
Thanks again!

Ben
