Data Markings Options for Project and TWC

We are using  Classification plugin in Cameo 24 with Teamwork Cloud for Config Management.  When I add sensitive element types to my project options, I would expect that they would stay with the project and be available to the next user that updates from the cloud.  However, we are seeing that our list goes back to defaults each time we update, so we have to rebuild it.   Is there a setting somewhere that would indicate that these options should be stored on TWC with the project?
