Gridview doesn't show calendar until "calendar" is clicked again

I created a page with the gridview template, and the calendar is technically there. However, it does not default to being “open” or “expanded,” which seems like odd behavior to me. The user has to actually click again, then, on “events” or “calendar” to get anything to show – and my users seem to not be figuring out that they need to do that; they just assume there are no events.

As a temporary workaround, I would be willing to just add a note to the top to let them know, but I can’t seem to do that, either. So…I’m baffled. What exactly is this page or template that’s displaying? It’s apparently not really the gridview, because I did add a note to that template, and it shows up once the calendar is (manually) expanded.

My Page, “Calendar” should be using gridview.php. This is what displays when you click on that page: http://scheonline.org/calendar-of-events/

When you click then on “calendar” (within the page, not in my navbar), you get this: http://scheonline.org/category/events/month, which is what I want to be displaying in the first instance.

Am I doing something wrong? Is there a setting I can change? If I could get this addressed, I would be just peachy; the capabilities of this plug-in are great! (Just wish the site integration were less complicated.)
