Padding of DoQ packets

While looking at DoQ traffic captured between the proxy and the AdGuard server, I noticed that the packets are not padded to the same lengths. This is curious, because when I asked the Support team I got an answer saying that padding was implemented and activated by default. Do I, contrary to the statement, have to set a flag in the dnsproxy command or is there something else wrong/padding missing?

my starting command for dnsproxy is:
./dnsproxy -l 127.0.0.1 --quic-port=8853 --tls-crt=example.crt --tls-key=example.key -u quic://dns-unfiltered.adguard.com –output=./log.txt
