Windows Admin Center の仮想スイッチで、チーミングの上にある仮想スイッチを見たんですけど、エラーになります。

英語版の画面も取得してみました。ちなみに、チーミング構成の上に仮想スイッチを設けていない場合でも、チーミング構成されているネットワークアダプターでプロパティが見えないエラーに引きずられていますね。。。
I also got the English version of the screen. By the way, even if you don't have a virtual switch on top of the teaming configuration, you're still being dragged into the error of not seeing the properties on the network adapter that is teamed up.
Get-NetAdapter

GWvSW vSwitch's NIC Property does not display.
