On the Student Tab of an event the 2 tables "Linked Opportunities" and "Interested as part of a learning Path" display details of opportunities where the interest is for the event or a learning path that the event is an objective for.

Both these tables display all opportunities whether they have been won, lost, or still in the sales process.

Ideally any opportunity that is won, lost, or archived would not be displayed in the list as there is no prospect of a student being added to the event because if the opportunity is won, they are registered onto the event.  If the opportunity is lost or archived then there is no longer an interest.

As a minimum the status of the opportunity should be displayed in the tables to indicate where in the sales process the opportunity is.
