Girl meets Rock! Duplicate chapters

https://mangafire.to/manga/futsu-no-keion-bu.728z7

Chapter 1-4 and 5-7 were originally released together.

For some reason these bundles of chapters all were put in multiple times on this website.

So chapter one is 1-4, chapter two is 1-4, and so on. Same thing for chapter 5-7

There's also an additional copy of these chapters called chapter 1.004: -4 and 5.007
