How to configure a DNS server by YAST2

Question

I run these commands to install DNS server dependencies on openSUSE Tumbleweed:

sudo zypper in -t pattern dhcp_dns_server
sudo systemctl enable named.service
sudo systemctl start named.service

To configure the DNS server, I'm trying YAST2 following this documentation:

sudo yast2 dns-server

I intend to configure example.com domain zone with IP address 1.2.3.4.

I have a DNS zone of master type:

My NS Records tab is:

My Records tab is:

However, saving the configuration runs into a problem:

Warning

Saving the configuration failed. Change the settings?

I couldn't figure it out. Can anyone help?

Update

Suggested by @JiriB I ran these commands and reconfigured the DNS server. But the observation is the same as before:

sudo systemctl revert named.service
sudo rpm  -qV bind
sudo cp /etc/named.conf.YaST-backup /etc/named.conf
sudo yast2 dns-server

Why do you start and enable named manually. Shouldn't YAST take care about it? I would start `systemctl revert named.service`, `rpm -qV bind`, then i would restore `/etc/named.conf.YaST-backup`, and start with `yast dns-server` again. — Jiri B, May 12 '21 at 12:46

The problem of:

Warning

Saving the configuration failed. Change the settings?

Got resolved by stopping the named service before launching YAST2:

sudo systemctl stop named.service
