Our databases are sorted according to the following criteria:
1. criterion = year ascending
2nd criterion = tournament ascending
3. criterion = round number ascending
If you start a database under Chessbase _ source indifferent - it can happen that e.g. the column sorting with the criterion "Year" is sorted ascending, but under the column "Tournament" it is sorted descending and vice versa.
The solution for the database in question in the database window is hidden in the Maintenance menu.
Mark the database icon - "Menu Maintenance - Sort Database" calls the corresponding dialog that allows to sort the selected database in ascending or descending order.
