If panel view isn't working, and you don't see the animation/fit to screen/page refresh options in the menu inside the book... then your comic/manga is not properly configured.
If you've gotten it from Amazon, I suppose you have to wait for an update? I'm not really sure where you go from there honestly. Sorry!
If you've sideloaded it, you can use the methods
in this thread to get them to show up properly.
There may be other ways to do this that I don't know about, but I've used that one and gotten great results. (Note: with the update you don't necessarily have to resize all the images to 758x1024. The fit to screen option can take care of it for you)
