Thank you for clarifying the hidden issue. 

For the Low Numbers Question there are a few ways to see these events listed below. But I do have some posts on the idea board about making the low numbers cancelled events easier to find. Thank you for your feedback! 

- For single date events (with no recurrence), you can find that event by using the Filter button on the admin event list to find events in the past with a status of cancelled. 

- For recurring events, you can go to that event's list of dates and check the box that say "Show past event dates" this will display cancelled dates at the bottom of your list. In this row you can also see the cancelled list of registrants and the reason they were cancelled (pictured). 

- If you go to the scheduler, and use the filter in the top right corner.

Hi there! Are you referring to hidden based on the "not public" setting at the membership level, or hidden based on the check box under the event's additional settings that hides it from Event Lists and Calendars so the event is only accessible through the public event URL?
