Hello, @greenative,
The shop page is coming from the WooCommerce simply go to the Dashboard >> Pages >> All Pages and simple edit the shop page then check the title of this page, also please make sure that you have set the correct shop page from the WooCommerce >> Settings >> Products then check back to your site after clearing the browser cache.
OR once try to check it with the default WordPress Theme like Twenty Twenty Two, just to make sure that the issue is with our theme or not.
If your issue is not resolved then please share your site wp-admin URL and access with us in the private content area I will check and let you know the cause of the issue.
Regards 8Themes Team.
