How to remove automatically generated books?

Dear readers, I have written just one book, "Vo Baat Un Dino Ki Thi", a poem collection in Hindi. But when I listed that book on Goodreads and made my Author Profile, some Mathematics books and other books are automatically generated by my name which I haven't written. I want to remove them from my profile but couldn't be able to do so. Will you provide your insights how to remove those unwanted books. Thank you.
