I'm using the Factbook Tool to look at a particular event - in this case where John the Baptist is arrested (although this issue is common across all events)
As the Events section shows, this particular event took place in the early stages of the public ministry of Jesus.
I would have expected the Save as Passage List and Open nn passages ... commands to just focus on the biblical passages related to the specific event as opposed to the containing event.

Is this a bug or is it actually supposed to work like this?
I'm using 9.14 beta 3 on Windows so reporting in the beta forum but I assume this has been how it works for some time.
