Modify authors list of a post (before, before last)

Hello,

I modifed the template for twig > inline.twig to change authors list in a post or list of posts. For exemple I need something like:
“By author_name | Verified by 2nd_author_name | post_date

I use <?php do_action('pp_multiple_authors_show_author_box', false, 'inline'); ?>
to display authors name and I changed the inline.twig with this code:

<div class="s-post-author">
        <div class="s-author-person">
            <span class="pp-multiple-authors-layout-inline author_index_{{ loop.index }} author_{{ author.slug }}">

                {% if loop.index == 1 %}Par {% endif %}
                {% if loop.index == 2 %}  Vérifié par {% endif %}
                    <a href="{{ author.link }}" class="{{ item_class }} author-post-meta"
                       rel="author">{{ author.display_name|raw }}</a>
            </span>
        </div>

Well it worked perfectly before but since a while it s not working anymore and I get:
author_name , | 2nd_author_name | post_date
or
author_name & 2nd_author_name

Would you have an idea why my changes are not taken in account anymore?

Thanks for your attention
