Adding Google Fonts and accessing the various weights in Advanced Styling

Hi,

I added a Google font to Enfold theme via functions.php file.

add_filter( 'avf_google_heading_font', 'avia_add_heading_font');
function avia_add_heading_font($fonts)
{

$fonts['Roboto Condensed'] = 'Roboto Condensed:300,300italic,400,400italic,700,700italic:latin';
return $fonts;
}

add_filter( 'avf_google_content_font', 'avia_add_content_font');
function avia_add_content_font($fonts)
{

$fonts['Roboto Condensed'] = 'Roboto Condensed:300,300italic,400,400italic,700,700italic:latin';
return $fonts;
}

I go to “Advanced Styling” and select H1 to edit, but under font weight, I can only see “default, normal, bold, light” – however, I can’t see 300, or any of the italic options.

What is the correct way to set my font-weights when I add a new Google font?
