blog image size

Hi, I am selecting to crop the image in the blog style but it does not take any affect on the page. I saved, updated, refreshed multiple times. I see other options change, but not that. I want the same image size for all the posts on the blog page like the demo and blog options suggest.

I don’t see a spot to send a private message to send admin info.
