Headline Blocks Overlapping with Unnecessary Black Backgrounds

Take a look at this page. Notice the headline blocks are overlapping and “blocking” each other (heehee).
The weird part is that the blocks have no background in the settings, yet the white text shows an overlapping black background. The “true” background is much bigger and already black.
Where is that setting hiding? How do I make white text with transparent “background” so that only the letters display?

For your information, the H1 headline is 3 different headline blocks — each with it’s own line. I did that for typography, line height setting was insufficient. If there’s a better way to get these three lines to appear closely together (other than making 3 separate headline blocks) let me know. A single headline is the official search engine preferred method, right? So there’s probably a way, but line height isn’t it.
