Standard Forecasting Profiles have Tuesday & March unchecked in decomposition groups in Demand Mgt

FYI to Product Development.

The standard Forecasting Profiles such as Forecast Shipments have Tuesday & March unchecked in decomposition groups in Demand Management module.

Other Decomposition Groups are checked as expected i.e. January to December, Monday to Sunday

Surely this is not expected and is an error in the application? Thanks
