How to edit the display of [eab_archive] with custom template in Events +

I created the page template in my theme directory called /archive-incsub_event.php and it works magnificently for the default events category (which I set as /events).

I am trying to rearrange things and add a featured image to the listings, but the template I added to my theme doesn't seem to have any effect on the output of the [eab_archive] shortcode (which is what I'm using to display events in different categories). I looked in the plugins/events-and-bookings/default-templates/shortcode-archive-default.php but any changes I make to that file don't seem to have an effect on the output of the shortcode.
