这些是我用来使用“menu\\u position”参数在“Master Artister Lookup”上方显示“Artists”的参数。但是，仍不能正确显示在菜单中

        $args = [
            \'label\'              => __(\'Artists\', SMF_CORE_NAME),
            \'labels\'             => [
                \'name\'          => __(\'Artists\', SMF_CORE_NAME),
                \'singular_name\' => __(\'Artist\'),
                \'add_new_item\'  => __(\'Add New Artist\', SMF_CORE_NAME),
                \'add_new\'       => __(\'Add New Artist\', SMF_CORE_NAME),
                \'new_item\'      => __(\'Add New Artist\', SMF_CORE_NAME),
                \'all_items\'     => __(\'All Artists\', SMF_CORE_NAME),
                \'edit_item\'     => __(\'Edit Artist\', SMF_CORE_NAME)
            ],
            \'supports\'           => [\'title\', \'thumbnail\'],
            \'hierarchical\'       => false,
            \'public\'             => true,

            \'can_export\'         => true,
            \'has_archive\'        => false,
            \'publicly_queryable\' => false,
            \'menu_position\' => \'20.1\',
        ];
