But you don’t have AdGuardHome active? This would mess with your DNS on the router.

So lets try to switch to the router: ssh root@192.169.8.1.

root@GL-MT3000:~# netstat -tulpen | grep :53 should show something like:

tcp        0      0 127.0.0.1:53            0.0.0.0:*               LISTEN      22125/dnsmasq
tcp        0      0 192.168.xxx.xxx:53       0.0.0.0:*               LISTEN      22125/dnsmasq
tcp        0      0 192.168.9.1:53          0.0.0.0:*               LISTEN      22125/dnsmasq
tcp        0      0 192.168.8.1:53          0.0.0.0:*               LISTEN      22125/dnsmasq
tcp        0      0 ::1:53                  :::*                    LISTEN      22125/dnsmasq
tcp        0      0 fe80::20f1:5aff:xxxx:xxxx:53 :::*                    LISTEN      22125/dnsmasq

vim /etc/dnsmasq.conf unfortunately is complete commented.
so i go with the sledge hammer grep dora /etc/* -r and got /etc/config/dhcp: option name 'dora'

here are all my configurations:

config domain                
        option name 'console.gl-inet.com'  
        option ip '::ffff:192.168.8.1'                         
                                                     
config domain                  
        option name 'dora'          
        option ip '192.168.21.14'   
                                         
config domain                  
        option name 'lupuse'  
        option ip '192.168.8.168'

Please check with cat /etc/resolv.conf if nameserver 127.0.0.1 is set (cat /tmp/resolv.conf should be the same, in fact is /etc/resolve.conf a symlink to /tmp/resolv.conf in a normal OpenWrt Setup).
Than check with netstat -tulpen |grep 53 if the listening service on port 53 is dnsmasq.
Make sure at the GUI (admin Panel), that AdGuardHome and similar services are disabled.

At last step for this part, you could check if the configuration is written in /etc/config/dhcp
