you confirm what I am seeing - when I insepct filenames ( via open path) I see new.epub in my working library, old.epub in my backup library, so I deduce that using edit metadata cause the epub book files name to change ( but not any of its contents)
I don't know how much about .opf file format, but trying to read it in notepad indicates that it holds NEW title...
I did suspect jacket.html as mentioned before but removing that & saving with sigil does not change the viewer behaviour. the OLD title was in jacket.html but that's now gone .
so the viewer can't be getting its info from there.
the i button shows NEW metadata. the epub file name is NEW, calibre's metadata.db I assume matches NEW metadata. where is OLD title hiding out ?
AHA - via tweak epub - the OLD title is in toc.ncx. I thought sigil zapped & replaced that; obviously it does not do a thorough job, I see OLD title in sigil F8 meta editor also.
so you reckon this will not update until such time as I do an epub to epub convert in calibre, or a send to disc/device operation ?
I don't much mind if that is the case, but i expected edit (book title) metadata to update all relevant locations - i guess it doesn't because calibre maintains a distinction between book & metadata, & only touches the former when asked to convert ?
