Add google font to enfold

Hi,

I’m trying to add a font to enfold but am having some issues. It is only sometimes rarely showing up. Here is what I added as a code snippet”

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

$fonts['Seymour One'] = 'Seymour One';
return $fonts;
}

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

$fonts['Seymour One'] = 'Seymour One';
return $fonts;
}

This is what I added to the quick css
`.header_color .main_menu ul:first-child > li > a { color: red; font-weight: 400; font-family: ‘Seymour One’, ‘HelveticaNeue’, ‘Helvetica Neue’, Helvetica, Arial, sans-serif; }
