If I may butt in:

I had a similar problem. It turned out that the story in question did not have chapter titles, and because I'd used an aggressive stripping pattern, it looked like the story weren't divided into chapters in the epub TOC. The solution was to simply use this:

Spoiler:

strip_chapter_numbers:true

chapter_title_strip_pattern:^([0-9]+[\.: -]+)?(Chapter *[0-9]+[\.:, -]*)?

add_chapter_numbers:true

I tried downloading your link, and had no problems. Even using only the default plus the above mentioned.
