Mystery solved...

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.
