[Resolved] Change of glossary term causes lost translations

Regarding our staging site:

Yes, we deleted the duplicate entries of "Jungfrau Region".

Sorry, we looked into the ATE directly. Now, we did it via sending a page to translation (ourselves in this case). The German strings are no longer empty if the English strings contains "Jungfrau Region". But, this now applies too when we now open the ATE directly. Yesterday, we had empty strings in these cases.

So, we now do see translation and they are marked as changed so we have to confirm them again. One point to note is that these translations are old versions. Edits we made later are gone. But that might be because we're on the staging site which is an older copy.

My translator also says this: "I'm not sure if all pages/posts that contain non-confirmed translations can be filtered by their WPML status. Last time I checked, some showed the status "translation is completed" (indicated by the pencil icon) even though there still were translated strings to be confirmed. I can't find examples now, so maybe that problem is fixed too. If it isn't, and if I can't be sure that filtering by the status "translation needs updating" (indicated by the cogwheel icon) is enough, I'll have to manually open the ATE and check for pretty much each page/post on our website, to make sure that all strings are confirmed and the updated translations are published."

Regarding the live site:
"after retrieving the translation, all glossary entries had duplicates": no, this only applies to the live site and we did not send anything to translation there. The duplicates seem to be generated spontaneously. We did not delete these duplicats yet because I first need to be sure how to fix the problem.
