I am going through the tutorial. When it came to applying section types to documents, I ran into this problem. Considering I am a newbie, I could be something wrong or not understanding what’s happening. However, since I’m using beta, I figured it might help to report the issue here.
Selecting folders in project settings does not highlight proper folders in binder. When exiting the project settings, the correct section types have been properly applied. So, it’s just the highlighting of documents in the binder that is broken. At least, I think it’s broken. Demonstration (animated GIF) attached.
