Colum sum in bold visibility


I have a report with a list view with 400 lines. When I open it I don’t see the sum in bold at the bottom of the columns, I see a - instead. But when I group by this report I have 70 lines and then the sum are correctly displayed.
Is there a way to force the display of the sum when I open the report with 400 lines ?


In my case I never select lines do you think it fall into the same bucket ?

Yes it is linked to the same problem which is the display of the sum when not all records have been read by the client.
