Cannot go back to Automatic DNS

Router: Velica

I have one set up DNS from Automatic to an AdGuard Domain. since then this domain always get set if I choose automatic. Also DNSCrypt wont work at all. Is there any way to get back to the DNS server my DHCP sends automatically?

Can you send screenshot? I cannot fully understand.

I changed once in this menu to AdGUard servers. Since then there is no going back to the ISP configured servers. And as the DNSCrypt Proxies are hanging after a few hours, I am essentially forced to use NextDNS or Cloudflare.

Is this a bug in the app? Maybe you can try using the web panel in your browser

tried now on the webpanel. i cannot find the same option, and vie DHCP the DNS is pulled, but not respected.
