Hi Protocoll,
The option doesn’t change the title tag, only the description tag.
Removing the Blog Name from the title currently isn’t possible through an option, and for a very good reason:
It’s what keeps the whole site together. Without “Rights Reporter” next to the title, Google and users won’t know where all articles belong to. “Post Title | Rights Reporter” makes sure Post Title gets valued accordingly to the Rights Reporter website. It’s actually very common practice.
A good read on this is found here:

And a official Google video about this:

I hope this clears things up!
However, if you still wish to remove this, you should use the following unconventional filter. I’m unsure if it imposes any side effects:
add_filter( 'the_seo_framework_title_args', 'my_title_blogname_removal', 10, 1 );
function my_title_blogname_removal( $args = array() ) {
//* Maintain default behavior on blog and home page.
if ( is_front_page() || is_home() )
return $args;
//* Actually only used to generate a description title.
//* Removes Blogname and Separator from title
$args['description_title'] = true;
return $args;
}
I hope this helps! Let me know if you have any more questions ??
