MacOS NextDNS with Private Relay works for a few minutes only to switch back to Private Relay DNS

As the title suggests, it works and then it doesn't. The filtering also doesn't work after a few minutes, I'm attaching a video. I experience this behavior both with the neatens apple profile and the Mac app. I would like to mention that it works fine on iOS with the same settings and Safari continues to use both private relay as the VPN and NextDNS as the DNS.
