B48-saved-Indicator-Set-not-retained-in-Workspace

With Build 48, I have to drop an Indicator Set on each Workspace after I open the Workspace. Before Build 48, the Workspace opened displaying the Indicator Set that I previously saved with the Workspace.

My normal process is to
A. Open a chart.
B. Drop indicators on chart to display what I want to see. For example a 20 period SMA, a 50 Period SMA and the upper and lower bolinger bands.
C. Save the indicators as an Indicator Set with some name.
E. Develop a Strategy and save it.
F. Open a chart. Drop the Indicator Set on the Chart. Drop the Strategy on the chart. Then save the combination as a Workspace.

I can then open the saved Workspace use it for my daily trading.

With build 48, I open the saved Workspace and the The Chart and the Strategy show up, but not the Indicator Set that I saved with the Workspace.

I have the default Indicator Set in Preferences set to "None". This is because not every one of my Workspaces use the same Indicator Set.

The folowing code is from one of my Strategies.

CODE:
public override void Initialize(BarHistory bars)
   {
   LRSI = new LaguerreRSI(bars.Close,Parameters[0].AsDouble);
   PlotIndicator(LRSI, Color.LightBlue);
         
        SetPaneDrawingOptions(LRSI.PaneTag, 10, 2);
   SetPaneDrawingOptions("Volume", 10, 3);

   DrawHorzLine(80.0, Color.Red, 2, LineStyles.Dashed, LRSI.PaneTag);
   DrawHorzLine(5.0, Color.LightGreen, 2, LineStyles.Dashed, LRSI.PaneTag);

   IndicatorBase volSMA = new SMA(bars.Volume, 50);
   PlotIndicator(volSMA, Color.DarkGoldenrod, PlotStyles.Line);
         
   trailing = true;
   stops = new TimeSeries(bars.DateTimes);
   //PlotTimeSeries(stops, "Trailing Stop", "Price", Color.GreenYellow, PlotStyles.Dots);

   StartIndex = 0;
    }

I don't know if the problem is because of the indicator plotting that is done in the code or not. I can just add a saved Indicator Set to a chart, without the above code, and save as a Workspace. Then I get the chart and Indicator Set when I open the Workspace in a new instance of WL7.

I would prefer that "none" in the preferences/default workspace means: "just leave everything alone - don't do anything!"
