Sorry for the inconvinence, the content that is rendering on shop page comes when there is no any widgets placed on Page Right Sidebar widgets areas. For this you can simply place text wdgets with no content .
If you are technically sound on wordpress , you can follow this :
Shop page have its own templates that is woocommerce.php file [You can find this on site folder-> wp-content-> themes -> encountesrs-> woocommerce.php]. So setting for full width page won’t work here. You need to customize this templates inorder to remove by coding.
Inorder to implement full width page templates please create new page and add this shortcodes on content area
