marketpress shop/all page title

Under Products > Store Settings > Store URL slugs, "Products List" is set to "/shop/all". How do you change the page title for that URL? Right now, it's randomly using a product's page title ("5051 Triathlon Aero Women's Top / Skinfit USA") and I can't figure out where to change it. Any ideas?
