It looks like they are gone, so either an admin removed them or you figured it out.
It looks like your settings are correct, – so I don’t know why it isn’t working unless you ave multiple subgroups that have the same name but different contents.
I would try again with a new group of groups, or reselect your groups in this view, save and see if it updates them. You can also do a date range in your original search when creating a group? (before a year or after a year. Is that how you set up one of them?
