Customers also bought with manual fill

Can anybody help. I use the customer also bought, but I want the filling to be manually. If I select this option, the product selected wil not show on the product page. If I select the filling “customers also bought”, the customers also bought will show on the product page. Does anybody know what I am doing wrong or what the code is to get it working?

Thank you for your response in advance.
