WHen I delete products andvariations via VBO some are still left I delete all my products and also the variations were deleted at the same time

but still after VBO delete under commerce/#overlay=%3Fq%3Dadmin%252Fcommerce%252Fproducts

some products are still left

why? I am attaching the image, there are empty products without variations inside that I cant delete

why is this happening?
In Drupal Commerce there are products and product displays. Did you delete the products and perhaps these are the remaining displays, which aren't displaying properly because you deleted the products?
