Duplicate H1 tags on all pages

Hello, I am using Sydney free theme for years, today I checked the source code of my pages, I found my website pages have the same H1 tags. How to remove site title from other pages except for the front page.

Hi,

Thank you for contacting us.

To help me find out the exact solution to suggest for H1 duplication, I need direct checking. Can you share links to your pages here in your reply?

Regards,
