Not adding rel=prev/next to homepage paginated pages?

We’ve just switched over to WordPress SEO after years of using AIOSEO on our website http://www.onedirection.net, and we’re loving it so far.

However, after inspecting the subsequent pages of the homepage posts, it seems they don’t have the rel=prev and rel=next tags added to them, whereas the tags and categories do.

Is there a reason for this?

Thanks,

Chris.
