I've installed calibre 5.31 today and I've found a problem when I edit metadata. If I edit the comments and switch from the preview window to the html window and I go back, the comments have been repeated a lot of times, and the edition goes sluggish. It's not a problem of the book because, for discarding that, I've edited a previous book and the same issue has happened. It makes impossible to edit comments for me.
