“Dupicate SKU” warning has vanished

Hello,

The warning that I’m about to save a product with a duplicate SKU isn’t showing up anymore. The product saves with a blank SKU and I have no warning that this has happened.

I’ve deactivated plugins and snippets. I’ve tried rolling WC back to 3.2.6, but nothing brings the error message back. I need to know that I’m trying to use a duplicate SKU to avoid a bunch of SKUless records in my shop.
