It seems that the site logo is assumed to be square in aspect. Since you used a rectangle, there is a blank space below your logo. A very hacky fix in the customizer’s Additional CSS:
.elementor-1517 .elementor-element.elementor-element-3ceadcc6 {
height: 90px;
}
For a more proper fix I suggest asking in Elementor’s support forum where their staff should know how to more properly fix this.
thanks for the detective work @bcworkz
Inside the header, I changed the logo size to custom and entered the correct dimensions. this fixed the bug.
