nextdns-v1.41.0 on UDM Pro warning regarding Content Filtering feature

I've upgraded to NextDNS 1.41.0 on my Ubiquiti Dream Machine Pro using the standard command:

sh -c 'sh -c "$(curl -sL https://nextdns.io/install)"'

I successfully upgraded and then pressed c to Configure NextDNS and receive the following error:

c) Configure NextDNS
r) Remove NextDNS

However, I have `None` selected under Content Filtering for both my default network and my isolated guest network. I've even removed the guest network entirely and the error still persists.
