Having problems setting up an exit node and advertised route with Tailscale on Unraid 7.2.2 server

I just upgraded to 7.2.2. I watched the 1.5 hr long Uncast video on how to use Tailscale. I want to use my Unraid server as an exit node and also have access to the LAN that the Unraid server is on via Tailscale. My settings are pasted below. Under the Use Exit Node dropdown box there are no options. The second and third screenshots are from the Tailscale web UI. Under Routing Settings I am able to set up and approve the exit node. But under the Subnet settings it says waiting approval and when I go into approve the Save button is not active it is grayed out.

Note I am not using a docker as an exit node - I only have one docker using Tailscale right now and that is Jellyfin and it is not set up as an exit node.

Here is my Tailscale settings screen:

Here is the Subnet and Routing Settings for my Unraid server in the Tailscale Web UI

Here is what I see when I click the Edit under Awaiting Approval for Subnets

Here is the setting for my Unraid server - maybe it is setup properly but then why can't I save?
