azw3 comic not rendering

I have an azw3 file for a comic, which displays normally in the Kindle app on my phone. When I load it into Calibre I find a bunch of non-pages (I hit page down and the display is white, page number doesn't increment, but if I do it enough times I get to the next page) and I find some corrupted pages (display all black or with a partial image.

I am at a loss on how to handle this. Any guidance could help.

Calibre 1.25.0 on Ubuntu.
