Holds to pull -list should not show only items that are available to loan. Now it shows items that are ordered or in process (not for loan value -1 or -2), if there are other items for the same biblio record there are already in use (checked out or waiting for pick up).
This is happening to us as well. Our Holds to Pull is showing items that are in a Not For Loan status of in processing. These items are not currently available for patrons.
