The translator didn't split the chapter, but only merged half the chapter parts (1-3 out of 6)Yes? That comment was about 20.1, while this is chapter 20.
If you were trying to imply it is the translator that split a chapter, then iirc I can refer you to some rule about how translators are not being allowed to split chapters further than the publishers did (but they are allowed to merge split chapters into one - thankfully).
