Widget Only shows one Event

The widget will only show events for today. If you entered other dates they won’t be shown until that day.

I finally got it working correctly. User error I believe. One final question, is there a way to change the format of the Categories? Like change font size, bold, and underline so it stands apart from the events that are listed?

You can style the category with the class tdih_event_type in your theme css file e.g.

.tdih_event_type { font-size: 20px; }

To make the category stand out. It is already bold so stands out from the entries already.
