Latest Version Causing Issues

Prior to updating the WP Job Manager plugin this morning, my job listings looked like this: https://imgur.com/oErZikp

I appreciated how clean the pages looked, and the images (which are always squares) weren’t distorted (just shrunk).

Now, whenever I create new job listings, they look like this: https://imgur.com/BJb1PEO

The image is stretched out to be a featured image (which I don’t want), AND the icon is distorted (turned into a 480×280 version of what was a 600×600 image).

Is there any way for me to resolve this issue? I’ve gone back to using the previous version of this plugin in the meantime, because I don’t want to be delayed in publishing new job listings. Thanks!
