VMware 6.7 all options in Single Sign on in VSphere Greyed out

[HOCompute]

Hi

I have a single host running in a lab with a VCSA configured. I previously managed to join VSphere to my AD domain however whenever I now go to edit ANY options in either Single Sign On Users & Groups or Configuration, all of the buttons are greyed out and I can't modify anything.

I am logged on with the Administrator@vsphere.local account.

What am I missing?

I believe that this was to do with the fact that I force removed the VSphere evaluation licence through the CLI as it had expired and was alerting despite the fact that I had valid licences in place. I think removing this forcefully broke something.

I have now deployed a new VCSA and all is working ok now.
