Portfolio archive page display issues

Hi there, I am migrating my site from wp.com to a self-hosted wp site ... on wp.com I had a premium site and was using Verity Pro, currently on my new site I am using Verity free. On the page where I am displaying my portfolio the featured image thumbnails are not displaying with the same orientation as they were on my original wp.com site. original wp.com site: https://drive.google.com/file/d/13bEErUfGvISktrh02sQXOe_boSW61luI/view?usp=sharing new self-hosted site: https://drive.google.com/file/d/1y1clo6Pc9y9X-f5TmHFkX6rKAbh0NmdJ/view?usp=sharing Any assistance is greatly appreciated.
