Power Designer 16 Stereotype change custom symbol bug

PowerDesigner Enterprise Architect
Version 16.0.0.3576 EBF5
OS: Windows 7 Professional

I have created stereotypes in the Oracle 11g DBMS xdb file for table and reference.  The stereotype, "Deprecated", changes the fill color, gradient, and line style for the stereotype's custom object.

The stereotype is applied to several tables and references.

Now I need to change the custom symbol properties for the stereotypes.  I expect the changes to be applied to tables and references that have been assigned the "Deprecated" stereotype.  Instead, these objects get reformatted back to the default settings!  I need to open each object and reassign the stereotype to get the formatting applied.
