Grabbed Sigil because a bunch of my epub books have the author and title swapped, meaning they don't arrange correctly. Tried using the meta editor in Sigil to change that, but now the Kobo app on my Android phone won't import them due to unspecified errors. I tried turning off the "clean with HTML tidy" option so that, in theory, the file would stay exactly the same as before I opened it, minus the metadata change. Still no dice.
Anyone have any brilliant ideas as to why editing the metadata to swap author and title breaks the file? They work fine before I make the change, but after, no go. Is Sigil changing other parts of the code that I'm not aware of and, if so, how do I turn that off as well?
