Expire events immediately, but not before the event

Hello,

We turned on "Immediately expire past events" plugin, but it looks like it is expiring events on the day of the event, before the event happens.

I am not exactly sure when this plugin runs or what it is actually doing. Is there anyway to make the plugin not expire an event, on the day of the event, if the event is not over. I.E. it is 5pm, event starts at 6pm or it is 5pm, event started at 4pm and ends at 6pm. We would like both of those to display.

our page is http://vozcycling.com/events/ if you would like to see what we currently have.

Thanks,
Rhek
