Book not showing up in library

I added a book earlier this afternoon. It is now late at night, HOURS and HOURS later, and the book is not showing up in my library. I see it in "Home", on "Recently Added", but it does not show up in my library, even when I type in the author's name.

Okay, so if I scroll through my library, it is there. But if I search author name, or title, it does not show up. In fact, it even says "No book found" in my library. I can only find it if I scroll through the rows and columns of my library. What is going on?

Search takes longer to load. Just be patient. It may be a day before it shows up.
