Aliant/Bell Connection Not Resolving Domains, using DNS Override on Router

I signed up for Pro a few weeks ago and things were running quite well, however last week all domains stopped resolving. My DNS settings were replaced with the ones from my.nextdns.io page.

If I revert DNS to my provider default everything returns to normal.
