White space between Hero Image & Menu Bar

I’m creating a new page and used one of the Page Builder pre-built layouts that include the hero image widget. I’ve used the Full Page, No Title template, so everything is stretching as it should be. However, I can’t find the setting to remove the white space above the hero image (between the site menu and the image) and below the hero image (between the image and the following content).

I saw a few questions like this one in the forum already, but the answers seemed to relate to CSS – of which I’m not much of an expert, so please treat me with kid gloves on this one. ;-)
