Advance custom field image field is not outputting result as expected [closed]

Hello I have this website shop page https://vitoslife.co.il/shop-2/ where the header image is actually set via ACF image field plugin for mobile and desktop. Here is my archive-product.php template which is overriden by my theme file

<?php
/**
 * The Template for displaying product archives, including the main shop page which is a post type archive
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/archive-product.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerceTemplates
 * @version 3.4.0

defined( 'ABSPATH' ) || exit;

get_header( 'shop' );

/**
 * Hook: woocommerce_before_main_content.

    //$thumbnail_id = get_term_meta( $term->term_id, 'thumbnail_id', true );

        <h1 class="woocommerce-products-header__title page-title"><?php woocommerce_page_title(); ?></h1>

        </div>
        
    <?php endif; ?>
</header>

Here is the screenshots explaining where it doesn’t output background image URL as intended.

Here are shop page and acf settings.
