Can't disable "Allow Anonymous Access"

I just installed ApacheDS 2.0.0-M21 and am trying to disable "Allow Anonymous Access" within my ApacheDS configuration using the following guide:
https://directory.apache.org/apacheds/basic-ug/1.4.5-anonymous-access.html

I cannot do this simple task using Apache Directory Studio.

When I uncheck the checkbox and save the config change, I get the following error:
Unable to save configuration.

• Changes could not be saved to the connection.
  java.lang.Exception: Changes could not be saved to the connection.
