There are two images in an .azw3 book, and using Editor I deleted one of them from the image section, and also from the reference from the metadata file. I save all the files, but then when I reopen, not only is the image reference there again, but the image itself reappears.
I've done an internal search of all files and there is no other reference to it, and yet it reappears every time.
However, text edits I make to the html files are saved and appear without problem. Can anyone suggest what's going on here?
