[AW10]

Firstly, from what I've read on the forum the bestseller should only show the most viewed from that category. However, it seems to show many products from that category - the site has only just gone online so it's impossible for all these items to have been viewed. Secondly, I added a subcategory and now in the main category it no longer shows the long list of bestselers but only the one product that is in the sub-category. Why is it only showing the one product?
