Songbook Title help!

I decided that I didn't want to have a title for my songbook for when I printed it, so I deleted the name that I had and pressed "rename" so that the title would be gone.  But when I try to click back it won't let me.  It just says [35] (number of songs) but it won't show me the songbook.

What happened?  How do I get it back?

Thank you!
