RQM categories in process template not working

Moderator note: This question extracted from answer on an old question. The context is about extracting a process template from RQM, modifying the categories in the template, and then re-importing the template to RQM.

Categories I add for Test Script are not working.  Here is my XML:

                                <category name="Category" scope="TestScript" />
                                <category name="Function" scope="TestScript" />
                                <category name="Test Phase" scope="TestScript">
                                    <value name="Developer Test" />
                                      <value name="Integration Test" />
                                      <value name="Performance &amp; Service Level Test" />
                                      <value name="User Acceptance Test" />
                                </category>   
                                <category name="Theme" scope="TestScript" />

It almost seems like items below the test case level are not supported.  Is this the case?
