page 2 of home page??

[ing]

So, I was checking which pages of my directory were indexed in yahoo, when I noticed something odd. It shows my home page with /?p=2 after it (mydirectory.com/?p=2) as a page in my directory. I typed in the url and it comes up, just like the home page, but doesnt show the subcats. Anyone else noticed this for their sites, or know why it's picking this up as a page?

Cheers
