Formatting Woes

So frustrated… Even after paying for formatting of my novel, Gateway, I recently discovered that a handful of my italicized phrases didn’t end up italicized. This wouldn’t be so bad if it weren’t for the fact that my heroine hears a “Voice” and I used the italics to differentiate between her thoughts, and Its thoughts. I've fixed the problem, but the book has been on sale for a month, so scores of people got a version that I’m sure is confusing. Heartbreaking… Anyone who thinks self-publishing is easy, either hasn't done it or doesn’t care about putting out a quality product.
