Hello Dan,
Yes I see what you mean.
However, this is what happens when you use a background image with text inside the image.
You can try by reducing the padding of the Welcome section with some CSS code,
@media (max-width: 767px) {
.hero {
padding: 110px 0 70px;
}
}
Place this in Appearance > Customize > Additional CSS field.
You can adjust the padding size to a number you’re happy with.
