Highlights from chapters are ordered wrong

[M31nevel]

First of all, brilliant plugin! Really happy to add my Kobo book highlights to Obsidian and use them to link my thinking.
But I noticed that when importing highlights from multiple chapters, that Chapter 11 (12, 13 etc) come before Chapter 2 etc. Could this be fixed?

Edit: I realize now that the error is a bit more nuanced, as it works well for some books (10.7 and 10.8 come after 3.6) but not for another book (13. and 17. come before 4. and 7)
