Orbi Pro SRK60 giving incorrect IP addresses via DHCP

Ok, this one has me totally stumped.  I'm trying to configure an Orbi Pro SRK60 system and running into the weirdest issue.  I've configured this to use a 10.0.0.x address range (with the gateway being 10.0.0.1).  Using static IP addresses, I can get all clients to successfully connect (it's a variety of wired, wireless, and IoT devices, about 30 in total including both Mac, PC, and IOS).  Using DHCP (both wired and wireless), some devices get an address of 192.168.1.30 while others get a correct 10.0.0.x address.  Those devices that get a 192. address all get assigned that same DHCP address with a gateway of 192.168.1.250.  That gateway address is not pingable by 192.x devices, it doesn't exist, and these devices have no internet access.  There are NO OTHER DHCP SERVERS ON THE NETWORK and the cable modem is just a cable modem, no Wifi, router or DHCP server.  Not that it would matter anyway, on the wirelessly connected devices, I'm connected to a password protected network with a custom SSID (meaning they would be using the Orbi DHCP server) and at times still getting a 192 IP address.

What's even more bizarre, the devices that get a 192.x address always have a DNS server of 8.8.8.8, which I know is Google's DNS, and I have no clue how they are getting that as that is not configured in the Orbi settings.  

Any suggestions on how to track this down?  I've been over all the settings and tried to track down any rogue DHCP servers to no avail.  But the fact that wireless devices are getting an invalid IP address is baffling to me.  

I'm running the most recent firmware on both router and satellite.  

Thanks
