Products are stored without title and product variations. Can't display them Such a weird thing has happened in my commerce kickstart 2 store. Somehow some products are in database but have not product variations and have not Title, so I can't display them in backend to remove them.

Is there a way to display those products in backoffice or I will have to delete directly in database? If so, is safe to remove them only in products table?

UPDATE:

I went inside database. I figured out that products that are not displayed in back-end search have not product variations anymore. Most of these products had Title Field and I could delete them by searching in front-end, clicking in Title link - this took me to node page's product. But now there are a few ones that have not Title. In front-end searching display them, but there is not a link to view node's product. So I think what I have are nodes without product variations. And the question What I do to deleted them remains.
I'm not working on Kickstart as I prefer to have a custom install of Drupal Commerce.

Commerce concept is that each product you create is a variation and you can use those variations in a display (content type)

If you can't see and delete products in the products list, you can create a view (page) displaying commerce products in admin mode (page url : admin/my-view).
Then add fields like : product id, sku, title and commerce product delete link.

But it's really strange to have products without title in yourdatabase... because you can't create product without title.
