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.

PowerDesigner 16 PDM Display Preferences - Table - Columns

PowerDesigner Enterprise Architect
Version 16.0.0.3576 EBF5
OS: Windows 7 Professional 

Issue:  Changing of Table display preferences for selected items only does not work after first use.

Steps:

1. Open PDM and diagram.
2. Select one table
3. Select Tools=>Display Preference
4. Select Table in "Display Preferences" Category
5. Change Columns setting.  Say Columns was not checked by default, but for specific table(s) you want to display all the columns.
6. Click OK
7. "Changing Formats" dialog should have "Selected symbols" already selected.
8. Click OK
9. Select another table in diagram
10. Select Tools=>Display Preferences
11. Select Table in "Display Preferences" Category
12. Settings in "Table" section should be same
13. Click OK
14. No "Changing Formats" dialog window is displayed and tables are not changed.

Work Around: 

1. Change the Table settings to anything else, apply them, and then change the Table settings back to what you want.
2. Right click table with desired display settings, select "Get Format".
   Right click target table and select "Apply Format"
   CAUTION: The entire set of format and display options will be applied to target table, so if fill color, shadow, line style, etc. are different in target table, they will be changed, too.

PowerDesigner 16 PDM Model Options not enforced and randomly ignored

PowerDesigner Enterprise Architect
Version 16.0.0.3576 EBF5
OS: Windows 7 Professional 

PDM Model Settings are set as shown below:


When diagrams were created, reference symbols were as displayed below:



Randomly, PowerDesigner chooses to ignore these settings and changes ALL reference symbols in ALL diagrams to the "Relational" Notation:



When this happens, I have to open each diagram, right click in the diagram white space, select Model Options, change the Notation style to anything else, click OK, open the Model Options again and change the Notation style back to Conceptual.

PowerDesigner does not let me change the reference symbol format using Display Preferences when this happens.  All the options are grayed out and set to "Notation".
