There’s no real direct fix for making sure a series description doesn’t duplicate into the meta description. There is one thing you can try though. MBT automatically programs it’s own SEO for your books, but there is a setting which can turn that option off. If you haven’t already tried this, go to: MyBookTable > settings > promote it will be the first check box on screen. It says, “Use MyBookTable’s built-in SEO features”. Deactivating that could fix your problem.
