Space between lines

I am having a hard time inserting a blank row between lines. I attempted to insert a row by pressing ENTER key after normal text format line in admin console, and it seems like a new line is inserted, however, when I save it and close the admin console, I see no effect of what I have just done.

For example, on this page I would like to see one empty row between the top photo and the words directly underneath, "July 2018" I have inserted <P> paragraph in the place, which has no effect visually.

What am I missing?
