I have a serious problem with my products. Last two days when I open Odoo. A lot of products have the same name, description, pictures, e-content, of other products. It seems that something is going wrong.

See my webpage (https://lekkerlui.odoo.com/shop/category/standaards-hangmatstandaard-97).

The different products are linked to another one. Has this something to do with duplicated items?

I don't know what is going on, and how to solve.
