Book Module changes not saved
An 2018 problem that seems to have re-emerged. My most recent Book will no longer save changes to layout; I can change photos in the existing layout but adding pages, changing text fields, etc are lost whenever I leave that book collection. I have made 24+ books in Lightroom over the years so I know what I am doing, anfd I cannot find a way around this. I have verified the catalog several times, run the backup so it checks and optimises the catalog, duplicated the book, exported the book as a catalog & verified, tried LR v14.5 and 14.0 but still will not save changes., I have created a new, separate book in the same catalog and that is working; only this particular book is the problem. If I add a blank page it sometimes gives an error "invalid page number position" or "... referenced" so somethings seems corrupted but the calatog verifies fine. I have gone back to earlier version of the catalog but the only version that works is before I made very significant changes so really isn't much better than redoing the whole book again and doesn't solve the problem.
Running LR Classic 14.5.1 on Win 11 all fully updated. 32GB RAM, 9800X3D and RTX 4070Ti.
