Could it be that you're using a DNS server with filtering (like AdGuard DNS) as an upstream?

You'd better use a non-filtering upstream with AdGuard Home.

It could be, but because the "DNS Server" field is missing in the "Response details" of Query Log Response column of the entry, i can't tell, i am using a bunch of upstream DoH servers. I am thinking of opening a separate bug about this.

[nicolaevladescu]

So i removed the upstream servers and tested them one by one, indeed i found the culprits that have extra filters:

• https://dnsforge.de/dns-query
• https://doh-de.blahdns.com/dns-query
• https://doh-fi.blahdns.com/dns-query

Sorry for the trouble.
