How to remove sample products from Home?

In a Development installation there are 84 pages of products on the Home page. How do I remove them?

I have checked the settings for the layout template, and there should (?) be only two products (manually added). If I check one of the products displayed on the home page (for example „Aerodynamic Aluminum Kioxi“) it is not set (as far as I understand) to be displayed in the Home category.

What am I missing?

Uninstall the demo plugin.

On the live server I installed without the demo products.
