@timmse I am on the latest 1.8 but facing same issue. In the editor, it shows {author_name} and {author_avatar} for the author selected at template settings > Populate content but doesnt show content of {author_bio} even in the editor. On the front end, example.com/author/john, none of the dynamic data({author_name}, {author_avatar}, {author_bio}) shows for the current author.
This is the conditions
