I mailed out today to someone that had ordered a couple books.  When I marked the first book as being mailed, it dis-abled that button on the second book - but left the second book still sitting on my "to be mailed" page.  Is there a way to get it off there?

For the second/third books going to one person... I click the button to print the label, but don't actually physically print it... just click far enough for the system to think I did.  Then the button for mailing the book becomes clickable.  Does that make sense?

thank you!
