Display problem with list-category-post 0.55

I started managing a Wordpress 4.1 site http://ift.tt/1JSqFom hosted by 1&1 running Travelify theme. I used the same data to run a Wordpress site locally on a MacBookPro. Both use plugin list-category-post to display posts. Before upgrading to list-category-post 0.55, both display category posts without excerpts. After upgrading, both display category posts with excerpts. The code shows

                         'excerpt' => 'no',

What do I need to do to display category posts without excerpts using list-category-post 0.55? Is there a way to revert back to a previous version?

Cheers, Luby
