Hi,
have a look at your server's Admin Console -> Resources -> JMS Resources -> Destination resources. That's where the topics and their relation to the MQ Server are defined. Check for both topics what the value of the "Name" Additional Property is because that's how the MQ server will call them. If both Topic resources point to the same topic in the MQ server you'll get the effect you describe.
