I’m using Dokan on a WooCommerce marketplace. I’ve already made the Shop URL field optional for vendor registration using filters, and vendors can now successfully register without filling that field. However, the Shop URL field still shows a red as

					<?php

// Add a filter to modify the seller registration form fields in Dokan
add_filter( 'dokan_seller_reg_form_fields', 'furnimax_override_shop_url_completely' );

/**
 * Modify the Shop URL field in the seller registration form.
 *
 * This function updates the Shop URL field to make it optional, remove the required asterisk,
 * and add helper text for clarity.

 * @param array $fields The existing form fields from the Dokan registration form.
 *

function furnimax_override_shop_url_completely( array $fields ): array {
    // Check if the Shop URL field exists in the form fields
    if ( isset( $fields['shop_url'] ) ) {
        // Set the Shop URL field as not required
        $fields['shop_url']['required'] = false;

        // Update the label for the Shop URL field to exclude the asterisk
        $fields['shop_url']['label'] = '<span>' . esc_html( 'Shop URL' ) . '</span>'; // Label without asterisk

        // Remove the 'required' class from the Shop URL field
        $fields['shop_url']['class'] = array(); // Remove 'required' class
