iCal bug/issue?

[foxpaw]

We're running WP events Aggregator to pull in Google iCal events, and while present and future events show up fine, past events cannot be hidden, and give a 404 error. I do see that for a "today" or future event, the event URL is .../events/eventname/ but for past events the URL is in .../?post_type=event&p=##### format.

We display the calendar via Events Manager, and I have "Display events as" set to "Pages"

I do not know if this is an issue with the Events Manager, the Aggregator, or ???
