Meta box Group with tags showing up twice in output

Hi

I am creating a custom product page on Woocommerce Products. In that layout I have a Metabox that adds bullet points, each bullet point is wrapped in <li></li> tags, set up in the advanced tab on the field creation.

But the output is showing twice, the first one has been duplicated by woocommerce, but its definitely not my code as I gave the <UL> tag a class and the first one has none.

Any Ideas

Here is the code I added to the woocommerce short description file

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly.
}

global $post;

$short_description = apply_filters( 'woocommerce_short_description', $post->post_excerpt );

    if ( ! $short_description )
        return;

    // Bullet Points
    $bullet_points = '<ul class="product__short-description--bullets">' .  rwmb_the_value( "product_bullet_point" ) . '</ul>';
    
    // The custom text
    $custom_text = '<ul class="product__short-description--bullets--red">
    <li>Please see our <a href="https://www.pinkequine.com/buyers-guide/">Buyers Guide</a> for current delivery times on Bespoke Products</li>
    </ul>';
      ?>
    
    <div class="product__short-description">
        <?php echo $short_description . $bullet_points . $custom_text ; // WPCS: XSS ok. ?>
    </div>

Here is the output screenshot
