marketpress products display reverts to grid when it should be list

Hi there,

I've come across a display issue when browsing product listings when they are paginated.

Under Presentation in MarketPress settings, in the 'Product Listing Settings' section, I have 'Product List View' set to List.

Everything looks find and is in list format when user visits:

However, clicking on Next Page shows the products in a grid format when it should be the listing format.

Can this be fixed please?

Wordpress 3.5.1
MarketPress 2.8.6

This is definitely not a theme issue.
