フォーラムを覗いていると、Discovery Interfaceで使用できる設定パラメータ周りの不具合があるようです。普通に使用している限りは問題ないでしょうが、allで設定しても!dynamicに戻っちゃう不具合みたいです。このしようもない不具合は次のバージョンで修正されるようです。

# now running v6.41.1 - after reboot - can NOT make changes to neighbor discovery-settings from cli or winbox

さらにWinbox周りの修正が行われていますが、これは同時に公開になったWinbox 3.12を使用することで修正を確認できると思います。
