[Assigned] Translation is not showing in the frontend

To sum it, the published post 68727:
- is translated in EN
- but the translations are not appearing in post
See image: published-post-68727-translations-made-but-missing

Now, it's interesting to look at post (n° 88414) just above the published one, filtered via using word ""encyclopedie" in FR ... which is at draft stage:
see image post-list-sorted-in-fr-via-key word-encyclopedie

It was generated via using plugin Yoast duplicate post.
Though identical to original one, it's declared as fully translated. What is not normal.

If you compare 88414 (FR) preview, with it's 88415 EN translatio, you see what was visually missing in original EN post is now visible (though in FR to be translated in EN). This means that the Yoast copy is better than WPML copy.

Of course, after, if I try to translate this duplicated post via WPML editor, it does not save. But at least, I have a better basis if I use gutenberg since the html and shortcodes are already there:
hidden link

Re WPML and the problem of memory ... it's always the same process of those undefined array key on media translatin ... and then the more or less fatal error via class-wpdb.php, as as managed by WPML
