Hi,
The "name" there is the name of each variant of your product.
You can set it by editing each variant via the Variants tab of the product edition page.
Same for the description.
If all the variants of your product have an empty description, then the description column won't display there.
It's basically a listing of the variants of your product. So based on how you configure your products variant the listing will change.
Regarding your sentence
Now it shows all other products in the same category
I don't understand what you mean. The product of your link is in the catering category. And if I go to that category's products listing, I see only one product. Furthermore, I don't see any products listing on the link you gave. Only the product page with the listing of the variants of that product. So it looks just fine.
