Getting a "set" on proxy exception error

Why is this happening?

Whenever I try to go to the "logs" section in NextDNS, I get this error.

I have NextDNS setup both as a "custom dns server" under my Mullvad VPN as well as at the Mac OS X level as a "proxy" profile, so I wonder if that's what's causing it?

The reason I set it up on both was because some Mac apps were bypassing NextDNS, and having both ON fixed that issue.
