Archive Block Wont Display Past Events

Site URL: https://swan-hypersphere-aweg.squarespace.com/archive-test-3

I am trying to get an archive block to link to past events (grouped by year) for our art gallery's website. But no matter what I seem to do, it will only link current events. When I press "Show Group Count" it gives an accurate number for these past years, but won't show anything when clicked. These past events are active and can be accessed through summary blocks, so it's not an issue with the event pages. 

This becomes more confusing when on the Squarespace help page for archive blocks it states " If you're displaying content from an events page, it's not possible to hide past events. " But I can't get it to show past events in the first place.

Am I missing something? Thanks in advance.
