I live in Rio de Janeiro/Brazil but I'm getting a French DNS IP

Hello all. 

So I currently reside in Rio de Janeiro/Brazil. 

NextDNS is routing my DNS traffic through a French IP. 

How can I fix this? 

I'm using NextDNS on my router which is a USG Security Gateway. 

Here's a screeshot of my router's config https://a.imagem.app/ATHEG3.jpg

Here's a screenshot of the French DNS https://a.imagem.app/ATHIXZ.png

Thanks in advance!
