edit link on quantity

Does anyone know why CS-cart puts an edit link instead of a quantity input box for products? We have some products that show edit and some that just show the quantity. But when we look for differences in the products we can’t see any obivious ones. The inventory tracking settings are the same and both have no options or combinations yet I see the edit link takes us to the combinations screen.

Do you have a screenshot of an example of your issue? I only see an edit link on my products that have options available to them which means I have combinations for those products. I see the quantity box only for products that do not have any options.
