After updating the new version I finished off a book and published only to find odd grey boxes around the first word of the title text and around the whole subtitle line. This appears only on iPads and iPhones. It doesnt show on any Kindle devices or online or on my desktop Kindle app, or Books in Mac which has me scratching my head. The book was done the same way as the last half dozen without a glitch. It did not show up at anytime of previewing in KP3 or the online Kindle previewer. I would upload a photo but I cant seem to get any link from Imgur to work.
