Hello,

Please go to file functions.php and find this block:

/**
 * List Google Fonts
 * @since 1.0.0
  */
function codeless_get_google_fonts(){
    $return = array('theme_default' => 'Theme Default');

    $google_fonts   = Kirki_Fonts::get_google_fonts();
    $standard_fonts = Kirki_Fonts::get_standard_fonts();

    $google_fonts = array_combine(array_keys($google_fonts), array_keys($google_fonts));
    $standard_fonts = array_combine(array_keys($standard_fonts), array_keys($standard_fonts));
    $return = array_merge($return, $google_fonts, $standard_fonts);

    return $return;
} 

Edit out to this:

/**
 * List Google Fonts
 * @since 1.0.0
  */
function codeless_get_google_fonts(){
    $return = array('theme_default' => 'Theme Default');
  
    $standard_fonts = Kirki_Fonts::get_standard_fonts();

    $standard_fonts = array_combine(array_keys($standard_fonts), array_keys($standard_fonts));
    $return = array_merge($return, $standard_fonts);

    return $return;
} 

Let us know.
Best regards!
