Magazine appeards incorrectly when uploaded!!!

When i open the uploaded pdf to view it online in flash format, it does not appear correctly. It shows 4 pages instead of 2.

Please go to (((http://issuu.com/qwmagazine/docs/issue12))) to see what i mean. There is a divide between each page and that is where the page should fold and not after every 2 pages.

I am using the latest flash update and have tried this on both updated versions of chrome and firefox but they both show the magazine incorrectly.
