Marketpress does not show grid view

Hey there, I have been trying to set up Marketpress for quite some time now but have been unable to do so due to this issue. Originally Marketpress was working fine (showing grid view) but now I can't seem to get it to work. No matter what I do the products seem to be showing in "list view".

Any help would be great!
