Hi @LoarsWoars it would probably help you to know that in new Evolve it’s currently only possible to create courses in English then localise them into another language using XLIFF export/import (see Course Settings > Translations).
I totally appreciate that if you want to do something like create a course in German this is far from ideal - but since the vast majority of our customers start with English then use a translation service to localise that course into other languages that’s the path we chose to prioritise for the initial release - but that’s certainly not going to be the end of the story when it comes to localisation!
I am guessing that from your point of view, what might be more useful is to be able to set the language of a course when creating it so that it a) picks up the correct label set and b) becomes the ‘source’ language for any localisation via XLIFF
If so I’d definitely recommend submitting that as a feature request, along with any other suggestions/improvements you’d like to see on the localisation front.
