Added this to functions.php of child theme as a workaround.
add_filter('woocommerce_package_rates', 'sort_shipping_methods', 10, 2);
function sort_shipping_methods($rates, $package) {
// Here define the primary shipping method key
$shipping_method_key = 'gls_shipping_method';
if (isset($rates[$shipping_method_key])) {
$rates1[$shipping_method_key] = $rates[$shipping_method_key];
unset($rates[$shipping_method_key]);
}
return isset($rates1) ? array_merge($rates1, $rates) : $rates;
}
add_action( 'woocommerce_after_shipping_rate', 'Mcs_shipping_rate_des' );
function Mcs_shipping_rate_des( $method ) {
if ( $method->id === 'gls_shipping_method' ) {
echo '<div class="shipping-method-description"><p style="font-size:14px; font-weight:400; margin-top:10px">Obave?tenje o prispe?u po?iljke u vidu mejla i SMS poruke kao i okvirno vreme uru?enja u rasponu od 3 sata.
