Category header not updating

I have installed Marketpress 2.8 beta4 and have set up a simple Products page ( with links to each product category. If I select the first category 'Home Decor' I am taken to a page displaying just the products in this category. All good. Now at the top of this page is the heading 'Home Decor' and a dropdown from which I can select other categories. Selecting another (such as bookends) shows all the bookends products but the heading still reads 'Home Decor'. Shouldn't this be updating to reflect the new category on display?
