Could you be more specific? By looking at the site I’m not able to tell if there’s something wrong or not.
In the meantime, consider making sure you have registered the image sizes that suit your site better:

I’m having this same issue where it’s resizing most of them well, but two of them just won’t work for some reason. I’m not seeing any server errors… is there another adjustment I can make?

It could be an issue with the encoding of the images. It may help to open them in an image editor and re-save them as a jpg or whatever format you’d like and then try regenerating thumbnails again.
This turned out ot be an issue with WPEngine and how they have the GD library setup incorrectly. To get around this we installed this plugin:
ImageMagick Engine
WPEngine is working on a fix for this but they were not able to give a timeline or even say it would be done this year.
