This might help you. I have an auction only site and used the code below. The time input doesnt work, you have to copy and paste the time stuff from the wcvendors auction bridge

<?php
/**
 * The template for displaying the Auction only Product Edit form  
 *
 * Override this template by copying it to yourtheme/wc-vendors/dashboard/
 *
 * @package    WCVendors_Pro
 * @version    1.3.9
 */
/**
 *   DO NOT EDIT ANY OF THE LINES BELOW UNLESS YOU KNOW WHAT YOU'RE DOING 
 *   
*/

$title = 	( is_numeric( $object_id ) ) ? __('Save Changes', 'wcvendors-pro') : __( 'Add Simple Product', 'wcvendors-pro'); 
$product = 	( is_numeric( $object_id ) ) ? wc_get_product( $object_id ) : null;

// Get basic information for the product 
$product_title     			= ( isset($product) && null !== $product ) ? $product->post->post_title    : ''; 
$product_description        = ( isset($product) && null !== $product ) ? $product->post->post_content  : ''; 
$product_short_description  = ( isset($product) && null !== $product ) ? $product->post->post_excerpt  : ''; 
$post_status				= ( isset($product) && null !== $product ) ? $product->post->post_status   : '';

There are several reasons why DIVI can be a headache.
First off, in areas they disable html markup, which is lame. At least they DID.. not sure if they still do.
Also, there is a smooth scroll that messes with pro dashboard pages.
We do have some code to deal with that.. I think it is this, in your theme/child theme functions.php:
