Total Pages in Book incorrect - how to fix?

[spacepope]

I just got a Kobo Sage, which I enjoy!
But I bought a book from Rakuten Kobo Japan and I have an issue...

As you can see in the attached images, "pages left in chapter" (at the top) is ok. But "pages left in book" (on the bottom) is clearly wrong, showing 24 pages in the book total.

The first 2 screenshots are from about 5% into the book, the 3rd screenshot is about 60% in.

This is causing numerous problems with this book - namely, I cannot jump around the book using the slider, and all my highlights won't show what % into the book they are located (it just reads %{1?})

Anyone have any idea on how to resolve this error?


EDIT: I exported the book into calibre, and sideloaded it - the page count went up, but it's still incorrect (showing 250 pages for what should be a 400 kobo-page book). The chapter page count is still correct, but the total page count is not working.
