The books I am having trouble with were split using Sigil, but I have used Calibre to add some metadata.
When I try to edit the metadat the metadata editor box pops up. When I click add basic the options box comes up (it didn't before, don't ask me why). However if I click on one of the options (date, language, etc.) the box closes but the new option is not added.
I looked at the other set of books, which were split by Calibre then edited in Sigil. The metadata box works there.
I have not checked every book, just a random sample. I attach the .opf for "A Child'd History of England".
(I just hate it when I have an 'interesting' case. I much prefer missing the obvious solution.)
Thanks for your suggestions and help! If worse comes to worse I can just create an .opf from scratch, but I'd prefer to know what and why, so I can avoid this in the future.
