You can check that the meta key exists before printing, like this updated snippet

add_action( 'wpo_wcpdf_after_order_data', '_additional_wooccm0', 10, 2 );
function _additional_wooccm0 ($template_type, $order) {
    if ( $template_type == 'invoice' && ! empty( $order->get_meta('_additional_wooccm0') ) ) {
        ?>
        <tr class="auricula-substitutions">
            <th><b>Auricula Substitutions:</th>
            <td><?php echo $order->get_meta('_additional_wooccm0'); ?></b></td>
        </tr>
        <?php
    }
}

It seems the issue is related to the mPDF version of the plugin. Try running the update for that plugin here and let us know how it works.

Thanks. This is a bit strange. The lines appear in Illustrator but are removed in Photoshop. When print directly from the browser without downloading the PDF are the lines still there?
