Problem with home page

Hello there. I’ve downloaded the theme Creativ Musician. I’ve installed elementor and I build my site with it. But there is a problem with the home page. I’ve put the right one into the WordPress customize section. But the website shown another page. From the top menu shown the right one but from the direct link there is another page and I can’t modify it in any way… How can I solve the situation without making again the site with another theme?

Thanks in advance
