Can't space between items on my Resources page

Whenever I add anything to my resources page, I can’t space down and put any spacing between the next link and the one above it. WordPress just leaves one line between all entries, making everything look bunched up. It worked fine until I didn’t get it published and had to redo everything, then it would’t allow any spacing. What is going on with this thing?

So far, I hate this WorPress author site. It never works the same way twice. As far as I am concerned, this platform is the biggest piece of junk anyone ever came up with. Editing is counter-intuitive and frustrating.
