Featured Images being Cropped

Hi there,
The other day I used a plugin to regenerate thumbnails on my website. After doing this, all of the featured images are now showing as cropped within the post page. The option “Crop Featured Image” is disabled in Highend options, but I still cannot get the full featured image to show.

(For example, full featured image is shown on homepage (http://servingrealness.com/), but is cropped horribly in post page (http://servingrealness.com/cheap-easy-vegan-breakfast-burrito-bowl-recipe/)

Thanks for your assistance!
