This dns leak test says I have a bunch of them, and I'm genuianlly concerned because I just started torrent with mullvand VPN yesterday
In express vpn's dns leak test though, it only shows eight so idk whats up. I switched to cloudflares dns but after seeing all those leaks I switched back to my normal dns
Just change your DNS config in the OS you use, I suggest you to use NextDNS but 1.1.1.1 should do the work too.
If you don't know how to do it just check out NextDNS.io for more details.
