I’ve been caught up but now I’m so confused. Why did it jump from chapter 8 to volume ...

Same

Sometimes the chapter names aren't accurate, but it does seem to be in volume 2 now. The old names didn't include Vol. but if it did, volume 1 likely ended at chapter 4. Counting from there, we get volume 2 chapters up to 7

And it could be misnamed too

Sorry, but anyways checked, chapter "8" and others are mislabeled, volume 1 concluded at chapter 5. I hope someone goes in there and fix up the list

Ohh thank you so much! I was scared to read in case I was spoiling myself
