Nested Azure WAC 2211 - cant select nics for virtual switch

Question

I am trying to setup a nested Azure for validation for a project - basically want to get familiar with the setup process and options. So I am ready to proceed when the time comes.

I done this previously with 2110 without issue but am now having issues when trying to do it with 2211 - and I'm not sure what I'm doing wrong or if i am hitting a known issue. Or if there is something new between the versions that i am not accounting for

Basically when I am creating a Cluster I get to step 2.3 'Virtual Switch' I can see the nic i want to select but cant select it for some reason - there is no tick box and i cant edit ip address etc, its not light grey as if it failed validation and have set it up with the same settings as the management network used and that validated fine.

Anyone seen this before?

Trying to figure if i am hitting a UI Bug or if its a validation fail how to figure out why it is failing

Both nics have trunk set and allowing all vlans
