I am confused, perhaps someone can help...

A book was requested from me today that is not on my shelf.  I did have the book about a month ago but someone ordered it.  Why would it be requested from me again?

I don't know?  You might look in My Account / Transaction Archive for clues.

Did that, that's how I figured out that I had it and mailed it.

I had that happen a couple months ago- it was a glitch.  Actually it was a book I've never even listed.  Just contact PBS and let them know.

All you have to do is cancel the order and the book will be removed from your shelf. There should be a box when you cancel to explain to the ordering member that this was a book that had already been posted and ordered by someone else a couple of months ago, apologize for the inconvenience. I would also then contact PBS about it, and check what's listed on your PBS bookshelf against what books you actually have available to make sure there's no other glitchy things going on.
