FYI I downloaded the version "with images" and am seeing no issues with location not being remembered.
I've tried both just exitting the bóok and going back into it, and exiting and powering off and back on.
This is on a Clara HD running a slightly newer f/w version.
Looking at the book with Sigil the only thing I wondered about was the name of the various internal files (for instance @public@vhost@g@gutenberg@html@files@15466@15466-8-0.txt.html). I realize this is a legal name but still....
*Edit* I am loading this as an Epub not kepub.
*Edit2* Bother I didn't realize your issue came AFTER adding a cover

Any chance you could just attach your editted version of the book?
*Edit3* If you are converting to kepub also attach a copy of the book from your Kobo.
