Hi @madvic,
Where exactly are you uploading the background image?
If it’s via the Background Image panel in the Customizer, then the image will appear in the background of single posts or pages. Note: It won’t appear on the background of your home page.
If you’ve uploaded the image via the Header Image panel then it will appear at the top of single posts or pages. Note: It won’t appear on the home page and can be overridden by adding a featured image to a specific post or page.
Let me know if that helps. If you can also provide a link to your site and explain exactly where you’re attempting to upload an image, I can guide you further also.

OK, thanks.
I think it will have a default header background.
Thanks
