I have fixed the issue with spacing. Contrary to popular belief, spacing does not help with ad revenue or to combat piracy. It is simply an issue with WordPress.
Copying and pasting chapters as plain text only have fixed this issue. Special formatting like Italics, bold text etc will be removed as result.
If I got a dollar for every time someone incorrectly assumes spacing or some other far-fetched idea increases ad revenue, I would be a billionaire.
