[Resolved] We are losing 'String Translation' translations regularly

Our site uses the ATE for all pages, but some texts must be translated in String Translation. Typically, these are the links behind buttons and code blocks (containing HTML). The ATE doesn't pick these up, so we go to String Translation to translate these. This is fine.

What we are regularly experiencing (and more and more, it seems) is that we make any change (small or big) somewhere on a page, and this resets some of the translated links and texts in String Translation. It doesn't seem to be constantly happening, but it's happening a lot. Enough to be annoying for the client and us. We have to evaluate and monitor the content of entire pages + all links for all languages after any change.

An example is shown in the screenshot. The link to hidden link was translated before, but there is some change, and now the "domain" of the 2nd row changes to page-builder-shortcode-string-61 for some reason. Instead of being smart and using a previously translated version (there are two!), it acts like it's a brand new translation, basically removing the translation of that link. It would help if WPML was a bit smarter here.

We also see that it sometimes just takes the FR text and uses that for the EN/DE translation, which is even worse. We are not sure how that happens. If we're unlucky, the translation is also removed from the front end, and then we have to go back to our translation documents to recover the translations. This is annoying and time-consuming.

We are seeing these problems on multiple sites. All Divi sites, which may be related to this problem. Hopefully you can help.
