"self-signed" field may be incorrectly indicating "no" values

See this entry:

```
2606:fe00:8000:2::133 | uticanational.com | utc-dns.northland.net | utc-dns.northland.net | ✅ | ✅ | ❌ | NO | NO | NO | Northland Communications (Northland Root CA) | Localhost | ncg.local, *.ncg.local, Localhost | 127.0.0.1
```

It indicates "self signed: no" but "Northland Root CA" is not a valid global CA, and 127.0.0.1 can't be in a cert.
