page_list with Visual Composer

Hi I’m using page_list with pages produced by WPBakery Visual Composer, to generate in a page the list subpages of that page. It works for the title of the page but I cannot visualize in the list the thumbnail of the images and the text included the the subpages. Can someone please hemp me? Thanks
