Oh I think that's normal.. Don't worry about this.
But you'll get other problems with an Ebook library. For example, I only have one free lending slot for the next four days. But I have 15 books reserved, of course.
I never know when I'll get my reserved books. If I get two books tonight, I can't download them both. I'd have to borrow one and skip the other one, which is extremely annoying if it's a book that you've been waiting for..
