Catalog/Inventory

I have requested that Populi make it possible for us to print shelf lists using LOC call numbers. I have also mentioned that Populi does not export CSV spread sheets with a correct shelf order of our Library of Congress cataloged media. Today I am attaching an Inventory image which verifies that Populi is confused with shelf order of LOC call numbers. If you will notice the image, Populi marks as a shelving error two books that are correctly shelved. Is it possible for Populi to write code to support LOC shelving mandates? That would also make it possible to export and print shelf lists.
