Hi Marcel,
That's odd. Can you send us your files via email? We'll take a look.
Edit: There was a bug where if you tried to import language data immediately after creating a new language, it wouldn't accept it. You had to create the language, switch to that view, and then re-open the translation panel to import the language data. It really only affected those that had exported their text in 531, since if you were using 540, you usually create the target language before exporting text in the first place. This should be patched in our next minor update. Or use the workaround above (create language, view language, then import).Regarding the
Change Language or
Set as Default button, if you only have one language in your lesson, the button is Change Language. The moment you add a second language, the option changes to Set as Default. See
this video. Hope that clears things up!
