[مغلق] We strongly recommend enabling WPML's automatic detection for image texts to avoid duplicated media...

I get this message from the admin : "We strongly recommend enabling WPML's automatic detection for image texts to avoid duplicated media fields and missing translations.", with this explanation link : https://wpml.org/documentation/translating-your-contents/using-the-translation-editor/switching-from-classic-to-advanced-translation-editor/?utm_source=plugin&utm_medium=gui&utm_campaign=cte-banner
This explanation link doesn't even talk about medias, it's all about the ATE.

ATE is a different topic, and I can't use it anyway, since I work with XLIFF files, which is a process known as not compatible with the ATE. So I remain on the CTE.

The button sends to the Media Translations settings, and more precisely to this setting: "Automatically detect best options for translating image texts (alt, caption, title) / Avoids unnecessary duplicate media fields and missing image translations."
What do you mean by "Best options" ?

All of this is very confusing.
Can you explain what's at stakes here?
