Images distorted in blog feed

Hello- The images seem to be distorted on my main posts page (my homepage) They are stretched and I can’t seem to correct this – Are there any functions or CSS that will help? I’d like the logos to fit in the box, undistorted – The settings in the media part of wordpress don’t seem to have any effect…

The website is here: https://www.thejobfather.net any help would be greatly appreciated ??

Thanks.
