P: Book Module - Used/Unused filters are not showing the correct selection

issue's fix confirmed, thanks for the update

Same here, it renders the book Module useless when yoiu  have lots of photos.

In the past I have been able to filter for 'unused' photos' when making books.  

This is a very useful option when making a book with hundreds of photos.

I am now using Lightroom 14.5.1 and this feature does not appear to be working.

Is this filter no longer available?  

Is it possible to reintroduce this filter option?

Bonjour, 

J'essaie de créé un livre avec lightroom.

J'avais l'habitude de construire automatiquement le livre (Disposition automatique), puis de retravailler le résultat (suppression des photos doublons/ se ressemblant ou que je ne veux pas mettre dans mon livre).

Ayant plus de photos que le livre accepte.

J'utilise le filtre "non utilisée" pour me permettre de gére un système de notation pour relancer après une nouvelle disposition automatique (toutes les photos ont 1 étoiles, je supprime l'étoile aux photos que je ne retient pas) . 

Le filtre "Utilisé" ou "Non utilisée" ne fonctionne plus avec la version 14.5.1.

je suis sur Windows 11.

Quel solution avez vous, car actuellement, je ne peux pas refaire de livre... ?

Merci beaucoup.

The Book module Filter (e.g. Used, Unused) still does not work in LrC v 14.5.1. So recent updates have not fixed this bug. Very annoying.

Looks like the bug is still active in the 14.4 version.  8/25/25 and still getting "No Filter" errors and can't sort by Unused photos to sort through hundreds of images in book module. This makes a book design a far more arduous task  - any updates on a fix coming soon?

1. Lightroom Classic version: 14.5 [ 202508061311-4cef2162 ]

2. Operating system: Mac OS 15, Version: 15.6.0 [24G84]

3. Create a new Book, transfer a few photos from the timeline to the book, try filtering based on "used/unused" status

4. There was a bug in LrC v14.4 that was not present in previous versions - the filtering of photos on the timeline in the Book Module based on the "used/unused" status does not work. I reported it almost two months ago and received feedback that the responsible team is aware of the problem and that they are working quickly to resolve it. However, the problem has not been resolved with the new version v14.5. The bug significantly slows down my work in the Book Module. I reported the problem again via chat support, but it was suggested to me to leave a comment about the observed problem here as well. I hope that this time the problem will be resolved quickly.

It dioesn't solve the Used-Unused problem for me.
