Owned books change to Read upon rating

Hey hey, dealing with a bug while trying to (finally) reorganise my books. Currently if you rate a book after having categorised it as "Owned", it switches it to "Read".

Rate the book first and then click "Owned".

And what shall I do if I want to add a book? I search for the book at listal. It says "no timen found", then I follow the steps to add the book, but in the end it doesn't work. I want to add some books of back-american author Marsha A. Hunt, and perhaps I want to add more books about rock and biographies that I've read and I cannot make the pages for those books. What shall I do? Thank you!
