What do I read next??

Hello, I need some assistance. I bought Jonathan Hickman's Vol.1 2 and 3 of X-Men, I wanted to get into Krakoa era stuff (its really good so far, read some X-Force, just chunking everything so far rn.) I am a bit lost however, on where Vol 3 picks up. It says it picks up on issue 16, when Vol.2 ends on issue 11. What gives, if anyone understands what I am asking lol. Do I need to go somewhere else to read issues 12 through 15?

I hope my inquiry is not confusing, thank you.
