How does the Events+ Plugin Call the page?

I'm having a heck of a time getting the Events+ plugin to show events on page. I've got it set to use the Plugin: fullwidth and the events are blank (and there is an event scheduled).

The Plugin:Calendar works, but I don't want it. I want the listed events.

The Plugin:smiley:efault shows "No event found".

The Plugin: Full Width shows "No event found."

Using theme templates (it's a custom theme I didn't develop, but took over) and I get a range of things that sometimes sort of work, and mostly don't, including a fairly blank page template.
