Events+ Archive shows…future events? Is that normal?

When I use the [eab_archive] shortcode, I get a list of future events. Well, actually I only get one future event: the one for this month. But I can add “lookahead” and get more future events. But there is no “lookback” parameter to get past events….?

I’m quite confused by this. Am I not understanding the difference between archived and expired?
