Hi,
I am currently trying to upgrade the system of a Cisco Firepower FPR1120 from version 7.0.4-55 to the latest stable release 7.2.5-208. Precheck passess successfully however when implementing the upgrade I get the following upgrade error "Fatal error: A maximum of two IPv4 and two IPv6 DNS servers is allowed."
I understand this is currently covered under the Cisco bug here
https://bst.cisco.com/quickview/bug/CSCwf68616
However, i've reviewed the dns settings on the FDM and I can only see two addresses configured unuder System Settings -> DNS Server (the default CiscoUmbrellaDNSServerGroup)
Show network gives this:

I'm unsure what other config settings need updating to allow this upgrade to proceed. What am I missing?
Thanks,
