The Jlive Feed is defaulted to be sorted by Upcoming. What this means is that for events that have multiple sessions, the next Upcoming session will be used to insert the event into the feed based on chronology.
So, just because one or more of the sessions have already ended, the event will still appear in peoples feeds.
Example
An event has sessions on
- Jan 1st
- Feb 1st
- March 1st
- April 1st
- May 1st
If someone is viewing the Jlive feed on Feb 28th, then they will see the upcoming event for March 1st.
