Hi,
A vendor applies to my store and enters store info, phone number etc, and then presses “apply to become a vendor”. When he/she are approved as an vendor, all the store info, phone etc is gone. If he/she updates it again, it works.

Here’s a print of my vendor-signup-form.php. I’ve only commented out the Social-tab.

<?php
/**
 * The template for displaying the vendor application form 
 *
 * Override this template by copying it to yourtheme/wc-vendors/front
 *
 * @package    WCVendors_Pro
 * @version    1.0.2
 */
