Apparently I didn't check the review box so a review got posted as text and thus, not attached to the book. I only noticed as I was looking over my shelves and noticed the book had no stars over it. I have to say, having multiple steps one has to complete to do a "there, I finished it, and this is what I thought about it" job is a bit...annoying. Too easy to miss something. Seems though that latest update might have at least attempted to fix that. There for a while back in the summer, it was an all-in-one thing.
Now if it would just put the start date when I move books to the currently reading shelf.
