Active users by group in Spark window?

I’'m rebuilding our OpenFire server. On our old one it listed all groups and you could collapse to see which users were online and offline in that group.

Since setting up the new server, I seem to have lost this setting. Seems to only list “Offline Group”.

Embarassingly, I can’'t seem to remember how to turn this back on.

I know that other people are logged on, but I have to search.

Thanks for any help. Spark and Openfire are great!
