Does kbin.run use a different mbin version to fedia.io?

I was testing kbin.run and noticed a different layout to kbin though when I had a look at fedia.io I noticed they use the same format as kbin.social.

Is the different design due to kbin.run and fedia.io being different versions of mbin or is it a setting the instance admins set up? I put a picture in the post to show what I mean.
