WP Page Navi is not

Hi There,

I have a little problem with this plug-in

http://lifecorp.com.au/blog/video/

In this blog page, At the very bottom you can see our clients pagination section

If I click to page 2 and so on it will just lead me to the correct URL http://lifecorp.com.au/blog/video/page/2/ for example.

But the blog content will be the same and will not show the content of the next page.

I hope you can help us with it.

Thank you in advance.
