By default all options on options table does not exported by this plugin, since it contain a lot of information and all information does not needed.
But you can use following hook to include all options:

add_action('advanced_export_all_options','prefix_add_all_options'); function prefix_add_all_options(){ return true; }

You can include needed options by using advanced_export_include_options filter hook

add_action('advanced_export_include_options','prefix_include_my_options'); function prefix_include_my_options( $included_options ){ $my_options = array( 'blogname', 'blogdescription', 'posts_per_page', 'date_format', 'time_format', 'show_on_front', 'thumbnail_size_w', 'thumbnail_size_h', 'thumbnail_crop', 'medium_size_w', 'medium_size_h', 'medium_large_size_w', 'medium_large_size_h', 'avatar_default', 'large_size_w', 'large_size_h', 'page_for_posts', 'page_on_front', 'woocommerce_shop_page_id', 'woocommerce_cart_page_id', 'woocommerce_checkout_page_id', 'woocommerce_myaccount_page_id', 'page_on_front', 'show_on_front', 'page_for_posts', ); return array_unique (array_merge( $included_options, $my_options)); }
