Product List page displaying HTML of text, and Archives and Archives by month headings

I have a Shop the Shirt page with a little text, a gallery of photos and a MArketPress eCommerce shortcode [mp_list_products list_view="0"]. Page looks OK, but the Products List page displays the text as HTML, and adds at the bottom the headings for Archives by Month
Archives by Category
No categories
Which I don't want. Actually don't even want a separate Products page since there are only 4 of them and are all displayed on the Shop the Shirt page.
The Shopping Cart and Your Orders pages also display Archives by Month, and Archives by Category headings, which I don't want.
Using Atahualpa theme and latest WP and plugins.
Can you help?
