Tasks/Summary not showing all groups

Tasks/Summary column - I can’t get groups other than “not completed” to show.

Can you give a screenshot that shows the issue?

Thanks for the reply. I forgot to canx the problem. I fooled around and got the other groups of appear. I had something to do with the sort function and caused the standard groups to appear. I now have “Monday”, “Sunday” and “Older” Tasks showing and I can get back and forth from “Hide completed tasks”. Previously, it would show only one group. Unfortunately, I don’t even remember its name but it was not one of the above. I couldn’t find documentation on which groups are available and how to choose which ones to display.
Thanks again.
