Problem with New Books List

I was looking at our new books list on the Library Home Page today and noticed a real problem. Almost all of the books listed have the message "No copies available...estimated wait 9 days..."
After talking with Darla, I understand that this message comes up because we check out these books to the NewBookShelf and the estimated wait time is how long they are still checked out on a 3 week limit, I believe.
But..... this is a real problem for our patrons! It looks as if we have none of these books available, when in fact, they are almost ALL AVAILABLE!
Does someone know how to fix this SIRSI screen?
