Improper Page Numbering/Formatting

[qwertyutee]

I have a ~300 page file in PDF format I'm trying to load onto my Sony PRS-300, using the latest Calibre.

When I load the PDF only 3 pages appear. The entire book is there, but it looks like this:

The reader shows page 1 of 3 as the cover
The reader shows page 2 of 3 as the rest of the book. I can move freely between pages, but the display never changes from "2 of 3"
Page 3 is blank.

This isn't a huge deal because the file remains on the proper page so I can still read through it, but it doesn't let me go to a particular page if I need to, because the entire text is on "page 2".

Any idea why this is happening? The file looks normal from what I can tell. I tried converting it to an ePub format, but it still suffers the same problem.

Appreciate any help or advice.
