Replacing GP Header with Elementor Custom Header

Hello

I have created a custom header via Elementor. When I apply it, both the Elementor header and the GP header appear in the mobile version of the website. The Desktop version is fine though (only the Elementor header appears there). Is there any setting I am missing? Please help!

Note: I have included the site URL. Have disabled the Elementor Header for now. Only GP header will appear.

Thanks :)
