For anyone wanting to know:
Chapter 9 from the CoroCoro magazine was split into 2 different chapters in the tankoban of Volume 2.
Chapter 18 from the CoroCoro magazine was split into 2 different chapters in the tankoban of Volumes 4 and 5.
and a few more later on to which I don't know since I don't have past volume 6.
The english volumes done in Singapore has the exact same chapters/covers as the Japanese one does.
The reason behind the chapter splitting is because...
When said volume is being made, if they're close to the CoroCoro issue version, they split said chapter into two different chapters.
Like for example in volume 2, chapter 10 is split only showing the first half of the CoroCoro issue version, while the second half is shown in Volume 3.
