Forecast scorecard: Final Error Measure sheet showing history data as '0'

Hi,

In the forecast scorecard workbook---> Final Error Measure worksheet, 'History Data for forecast window 01....' measure always shows '0' value irrespective of my selections in the wizard.

However, I can see history data in the other view i.e. Final Actuals vs Forecasts worksheet.

Is there anything unique to this view, or am I missing something here.

Note that, I have tried opening the workbook to display a forecast generated in the past (lets say forecast for 1-Jan-2015) or tried to switch RPAS_TODAY to a date in history, ran the forecast and still the history data for forecast window is '0' even though I do have historical sales.
