The custom Collaboration Message Definitions for inbound cXML is not found

Summary:

We have defined a custom collaboration message definition for cXML on the Manage Collaboration Message Definitions. After we have created the user defined collaboration message, we navigated to Collaboration Messaging Service Provider and the custom message we defined was not showing up.
How will we pick up the user defined collaboration message definition? The issue is only occurring in one of our dev environment.
