Cause

A property flag was disabled from prior troubleshooting and not re-enabled. 

Resolution

1. SSH into the SDDC Manager with vcf and then elevate to root.
   
   
2. Edit the domainmanager service application-prod.properties
   vi /etc/vmware/vcf/domainmanager/application-prod.properties
   
   
3. Remove or comment out any override flags in the properties file.
   

   # will override the defaults in prod profile
# this should only contain properties that we want to preserve on upgrade
spring.profiles.group.default=default,test
