Huge vertical space on browse categories page

Hi! When I go to http://en.opensuse.org/Category:Howto or any other of the categories I get: Category:Howto From openSUSE Howto Documents The "Howto" document is well known within the Linux community, and is a detailed "How to" document covering a specific topic. <a huge vertical space> Articles in category "Howto" There are 55 articles in this category. What is that space for and if it has no use, how can one get rid of it? Sven
