Hi @johnpeterm it looks like you just have some warnings. Reading through them, some appear to be telling you that you’re missing some of the font-families declared in your CSS (Lora, CormorantGaramond), and others are letting you know that the .mobi file is declaring some CSS style properties that aren’t supported by Kindle readers.

Thank you. @SteelWagstaff
