As an example, here's the way they're being sorted.

Rom 10:17

Rom 11:29

Rom 12:1

Rom 1:16

Rom 3:10...

So, if there were a chapter 30, it would come before chapters 1-29

Good catch, Pike!

Thanks for this. We'll fix it.

Are you sure this is happening in notes, too?  The code doesn't look wrong there.

I stand corrected. The problem doesn't exist in Notes; only in Bookmarks.
