Related Categories showing Vertically, instead of Horizontal (Web Link Given)

[Acropoli]

Hi All,

Done a search on the forums with no applicable results, so hopefully I'm not reposting an existing question.

My VM2 Store, by default, lists my categories Horizontally.  Perfect!

Unfortunately, Related Categories and Related Products list themselves vertically for some reason, wasting a lot of screen space. 

Example here:  http://webbyte.co.nz/index.php/store/financed-systems/start-here-base-system-detail

Is there something I'm missing?  This must be an easy fix.  Thanks in advance
