Headings have reversed
The first upload of the ebook shows the correct size for Heading 1 and Heading 2.
I've had to make some corrections and in the last 2 uploads the size of the Headings have reversed - Heading 1 is in 12pt and Heading 2 is in 16pt. I didn't change those! Nothing has been changed in my original document and I double-checked the formatting before I uploaded this last time.
If I just reverse them, then I get an error message. How do I correct this?
