iBooks and saving PDF as original
Hello,
I have an annoying problem.
When I add PDF to iBooks I can not save the original document. Each time a document is a copy.

It means "You can not change the original document; it has been duplicated with your changes."
This is frustrating, because I just can't use cmd + s
I hope for quick help.
Thanks. 🙂
