Problem with pagination

[Waleed]

Hey.

So I'm using the YTV gallery application on my forum

http://sharree.com

Here's the issue:

On the homepage it displays 3 pages, which is correct

However when I go to the prefix links the pagination still displays 3 pages, even though there should only be one.

Any ideas what the problem is here?
It's not a theme issue because I've tested three other themes and still doing it.
