Additional context

I imported the book from Calibree on desktop

And I edit metadata in calibre-web

Maybe there's a confusion on the old/new book title before/after renaming. not sure how to consolidate these ?

Please perform a library maintenance in calibre (should be in library menu), there is something wrong with names in the database and in file structure
