Broken Single-Event Links from Widget in 4.1

I use the sidebar widget to display upcoming events at http://www.revereteachers.org.

Using 0.4.0, I configured everything how I wanted it, including enabling links from single events to the event page at http://www.revereteachers.org/calendar, using shortcode id: 1.

After I updated to 0.4.1:
Single Event Links from the Widget no longer direct to the calendar page. Instead they open to the current page or post with “?event_id_1=#” added to the URL, which makes the widget display only the event with that number and a header saying Event Information which is typically not there.

From the front page, the link directs to the first post in the news ticker, with the event list slug.

From on the calendar page (where it is Supposed to point) it reloads the calendar page with the incorrect sidebar, but the url changes to
“?event_id_2=#”

I’ve disabled widget single-event links, and added a less stylish link to the calendar. So, functionality is fine, but I’d prefer to go back to single event links.

These same errors occur when I enable the twenty-eleven and twenty-twelve themes (which don’t have news sliders).

This problem originated when my only active plugin was event-list.

Thanks for any help you can offer.
