Every time you add a line break in wikitext, unless it's within a parser function, it creates a new paragraph. So in the following code, for example, you have two paragraphs being created regardless of the output/result of your parser functions: < NEW PARAGRAPH < NEW PARAGRAPH

So to avoid that empty space, you'll need to compact your parser functions so there's no line break between the end of one and the start of the next.
