While I appreciate that you're translating this, I have to ask why you're splitting the chapters in a different way than the way it was originally published.
This supposed "chapter 2" is still part of chapter 1, anyone who clicks on the French or Portuguese version of chapter 1 will find out.
If you're splitting them into shorter parts because it will take you way too long to translate a whole chapter, I really recommend you to reconsider and publish the chapters in their original format. People won't mind waiting a little longer for the entire chapter, I promise. Right now, this format is pretty annoying.
