Spacing between paragraphs and h2 sub-headers is inconsistent

Hello,

Loving the Kale theme so far.

One issue I am having is the spacing with my h2 subheaders.

I want one line of space above and below each h2. I type this in for my posts.

Yet for some of them, it doesn’t work. If you go through the posts on my website, buildingupbucks.com, you’ll see the inconsistency.

Any way to fix this?
