Once the Author field has a value, I can't remove it or change it via any of the editing options (command line, infoedit, or details pane). I can insert an author if the field is blank, but then it's there for good. The other fields work fine, it's just the one. The anonymizer will empty the author field along with the rest, but that's not the way I want to go. Trial version 3.1.1.0, Windows 10 64-bit.
