Why no paragraph breaks?

This is VERY annoying.

When you type out content in this New Blue theme and hit “return” to go to a new line, it does not start a new paragraph. Instead, it goes to the next line down. (you only realize this after saving the post and viewing it in a browser)

But if you put 2 spaces after a paragraph, it ignores the second one and you’re still left with no break!

So what I’ve had to do is MANUALLY insert br tags everywhere throughout posts and pages.

C’mon, there’s GOT to be a fix to this. None of my other themes do this.
