Page preview varies

I’m new to WordPress and have not published my website yet. I’m using the free version of Elementor. When I preview a page in the theme customization section the header shows my logo with a navigation menu. When I’m editing a page with Elementor and I preview it, the header just shows the name of my company – no logo or navigation menu. Will my header appear correctly once my website goes live or do I need to change some settings?
