check the setting in wp-admin->theme option->homepage featured category->featured layout style.

you must be using ‘medium’ not default.

but i set medium only please see this image https://i.imgur.com/ohJKGM8.png

its the home setting->choose your featured category layout->all medium, choose default instead.

now it’s came like this https://i.imgur.com/XFToMUe.png

seem like you still using v1.6.3 of the style.css, better update it or add this to theme option->custom css

aside.home-feat-cat .apost .feat-thumb {width: 100px;}
aside.home-feat-cat .apost .feat-right {margin: 0em 0em 0em 110px;}

you can’t, all your thumbnail is cropped at size 100×60, example
