Page naming configuration is not reflecting properly even though the configuration is defined properly. For example we removed the "Show Domain" tickbox while defining the configuration and saving the configuration. However the page name still shows the domain name in the page name registered.
Controller pushes naming configuration to eum server every minute. In this case same license is used across two controller. Hence both are pushing the naming configuration for the same eum account. So the eum configuration from one controller where we have defined the configuration properly is getting overwritten by the controller which does not have this configuration.
We should not be using the same license across multiple controllers. If we are moving a controller from one environment to another we should shut-down the previous environment to remove ambiguity described above.
