residential proxy being detected

I bought a residential proxy. When I go to whatismyipaddress it shows that it belongs to a legit isp.
I plug it into antidetect browser and go to that website that detects if your fingerprints are natural, I think it's called pixel scanner or something.
it says it's highly likely that you are using a proxy.
I am just wondering if it's the proxy's fault or antidetect browser is doing something wrong.
have you ever had this problem? what's the solution?

change your dns to google dns. That can detect via your dns

There are 2 reasons here, either a bad proxy or a bad antidetect. You should use higher quality proxy and connect it to an antidetect that updates the browser regularly. I use gologin and bright data proxy and don't experience this problem on pixelscan

I tried to sign up for bright data and they are so intrusive, they want to know everything about your life.
