Sessions are ordered by name, not by date.
I think that is better order the sessions by date, as we have in ADNM.
I’m not sure, whether I understand or not, but:
You can choose your own order, just click on collumn header as: Occured/Event id/Object… This way you can sort listed events as you need.
Note: Events are still under construction 
Sorry, I refer about sessions in the folder structure (see picture).
