Here's what I'm doing: I'm converting pdf files to docx (using Adobe Acrobat X) then editing said docx files and saving them as Web Page (filtered). Then I convert them to MOBI with Calibre. Everything works as it should except TOC created by Calibre.
Chapters in Word look like:
PART I
Chapter One
Chapter Two
...
Chapter X
PART II
Chapter XplusOne
Chapter XplusTwo
...
Chapter Y
PART I and PART II are level 1 and the rest are level 2.
The TOC I get from Calibre looks like:
PART I
PART II
Chapter One
Chapter Two
...
Chapter Y
Why is this happening? Should I change something in filtered html file? Or change some Calibre setting?
