Directory Pagerank

directory-sj shows different values

[WebWalla]

The Google directory at directory-sj.google.com is showing different pagerank values in various categories I have looked at. Don't want to start any typical pre-dance nervousness, but can anybody give a suitable explanation for this?

It's the old directory.
