After you have changed the parameters you have to click on the New button in the toolbar to generate a task which uses the new parameters. You can also call this action from the menubar with Task New. This will reset the statistics. To avoid that, click the Next button to proceed with the changed parameters.
Tras modificar os parámetros ten que premer no botón Nova tarefa na barra de ferramentas para xerar unha tarefa que empregue os novos parámetros. Tamén pode chamar esta acción desde a barra de menú mediante Tarefa Nova tarefa.
