The values you have circled are not part of the custom fields. They are part of the configuration data of Simple Fields. You can find them in the dadabase in table wp_options in the row with option_name=simple_fields_groups. Field option_value contains a string of serialized data.
You can read the option with WP function get_option(). It is deserialize automatically. Use var_dump() or a plugin like SM Debug Bar to display the content.
