Cause:
Basically, Auto Generate Client ID will generate a new client ID every time a connection is made to the JMS Server.
Resolution
When using Durable Subscribers, you should manually set the client ID for the JMS Connection. See the attached screenshot (Filename: clientID.png). In this screenshot, Client ID is set to "CID". Once the Client ID is set and the application is started, EMS Admin will display the following output when command "Show Durables" is executed:
topic.sample CID:TestSubscriber
topic.sample CID:TestSubscriber
