EPUB File opening at wrong page

[immune.doyens]

Hi all,

I have a Kobo Clara Colour running firmware 4.45.23697. When I sideload an EPUB and open it for the first time — completely unread, no prior history on the device — it opens at page 333 of 671 instead of page 1. The cover image displays correctly, but the position counter shows 333.

Things I have already tried:

- Confirmed the file has no saved reading position (removed META-INF/calibre_bookmarks.txt from the EPUB)
- Changed the book's UUID so Kobo has no database entry for it
- Deleted the file directly via USB (not just long-press Remove) before re-adding
- Verified the file is not present on the device before copying the new version over

The position 333/671 is almost exactly 50% through the book every time, regardless of changes to the file. Navigation via the table of contents works correctly — selecting a chapter goes to the right place. The issue is purely the position counter and the initial

It has 17 spine files (a titlepage.xhtml plus 16 split HTML files) and embedded fonts.

Has anyone seen this behavior on the Clara Colour or other recent Kobo firmware? Is there something in Kobo's SQLite database that persists even after deleting the file via USB? Any pointers would be appreciated.

I’ve attached the file for reference.

Thanks

EpubCheck?

None of the errors should cause such a problem. Besides, the page numbers listed by the OP make no sense as ADE shows only 196 pages. So there's no way this could be 671 pages.

I had something very similar to this happening with a book on my Kobo Touch a few months ago.

It opened at the cover image but the page count below was double what it should be and would show the book as being halfway through, even though it hadn't been read.

Didn't matter what I changed, it kept doing the same thing. I eventually had to show it the error of its ways by setting Sigil on it. Everything went in the bin apart from the basic HTML pages, the stylesheet and the images and I rebuilt it from the ground up.

Bit of a nuisance, but sometimes it's the easiest way.

The eBook the OP attached (before it was removed) is from Microsoft Word and not a legit version. I didn't see anything in it that would cause the problem.

I'll scrambled it and attached it here so maybe someone can figure out what the problem is.

Ah. Well that probably wouldn't have helped!

Mine was legit though, hence going the extra mile to actually be able to read it without it irritating the hell out of me.

Thing is, there has to be something that causing the problem. I should load the eBook on my Libra 2 and see what happens.
