Hello Ralf - and other translators here. Regarding your post about missing translation icons in a couple of pages in German (they were not missing in other languages) our developer Aya has spent some time exploring this and now has an explanation, and I think it will be useful to all, so I am pasting it here:
Apologies for the delay on getting back to you regarding this issue.
After many hours of debugging 😃 there's a tiny non-printing character called
that was present in the Deutsche translation for the mentioned pages which was causing the translation filter to break and not show the translation button , after removing this character i can access the translation button again.I'm not confident on what exactly got this non-printing character into the translated text but maybe the text was copied from a word processing software (Microsoft Word or word pad ).
