Good afternoon @lamiclama,
We appreciate your interest in our products as well as reaching out! I’m happy to assist you.
When you say you want to remove the white area, are you talking about the section that says Event Archives? If so, this is actually a component of your theme rather than The Events Calendar plugin.
If you dig into you theme options, there may be an option to customize the header areas. If that doesn’t work, you can use CSS to remove the area. The element you are looking for is called .parallax-section–header
The following should point you in the right direction. But keep in mind that adding this CSS will remove the header from every page, you may be able to target the page id with CSS and only apply it to the page that you would like.
.parallax-section--header {
display: none;
