User Error or Did I Find a Initialization/Setup Bug?

I recently took possession of a shiny new Gold SE. It's a good looking unit and runs just barely warm, which I like. After going through setup, which was a breeze, I had the unit up and running in just a few minutes.

However, when I was going through the settings on my Android Phone, app V 1.65.1, I found to my dismay that the Ingress Firewall was off. Huh? I'm not sure why you can turn it off, but there it was, off. I immediately enabled it and it has remained enabled since then on it's own.

I'm not sure if I somehow botched the initialization/setup but I thought that folks should be aware that this possibility exists. Here's where the setting is: Rules-->All Devices-->Ingress Firewall (it's not searchable)

I'm really enjoying the window into my network and the ease with which I can keep my daughter's ipad safe. The product seems solid. Overall I am happy.
