Turn the "include" settings off by default and only include these if absolutely necessary. These additional settings (Quarter totals, Year to date, Year to go etc.) will be included in all modules with the model calendar as the time dimension. Thus they will perform calculations on these subtotals. Consider if you really need these values for all modules with the Model Calendar.
Note, you can specify different "include" settings for different Time Ranges, although by default Time Ranges will inherit the Model Calendar settings.
