I Need Help pfSense DNS

Hello, I have an issue. My NextDNS keep telling me I am using Cloudflare and I put NextDNS on my pfSense. My DNS setup on pfSense is as follows:

Under the tab: System > General Setup:

These are in the server (x is representing numbers and letters of the DNS)

IP: 45.90.28.xxx - HOST: xxxxxx.dns.nextdns.io

IP: 45.90.30.xxx - HOST: xxxxxx.dns.nextdns.io

Under the tab: Services > DNS Resolver > General Settings:

Within Outgoing Network Interfaces, I selected ProtonInterface. (My ProtonVPN interface)

I enable Strict Outgoing Network InterfaceBinding.

I enabled DNSSEC.

I enabled DNS Query Forwarding.

I enabled Use SSL/TLS for outgoing DNS Queries to Forwarding Servers.

It seems that the DNS server don't want to change even if I deleted my previous DNS which was cloudflare (I usually use it for setup and then later change it)

I am curious if I missed something or if I did something wrong?
