The 3 and 4 columns grid hide the sidebar by design. That is to avoid page clutter. If you want to remove it add the following in your child theme’s functions.php file:

add_action( 'after_setup_theme', 'enlightenment_child_remove_grid_layout_filter' );

function enlightenment_child_remove_grid_layout_filter() {
	remove_filter( 'enlightenment_current_layout', 'enlightenment_filter_grid_layout' );
}
