Can’t remove Login and register links

Testing this before I go live with clients password is gordie
Tried this
// Add this to your theme’s functions.php file or use a plugin like Code Snippets
add_filter( ‘sunshine_main_menu’, ‘custom_sunshine_main_menu’, 999 );
function custom_sunshine_main_menu( $menu ) {
unset( $menu[100] );
unset( $menu[110] );
return $menu;
}
and this
// OR, alternatively add this to Sunshine > Settings > Design > Custom CSS
li.sunshine-login, li.sunshine-register { display: none; }
but links still there

The page I need help with: [log in to see the link]
