SKU not being applied to new bulk created products

Hey there, first of all thank you so much for this very handy plugin ??

I use WP Sheet Editor to bulk create new products and I save them as drafts so I can fine-tune them before publishing. But when I hit the bulk create SKU button, the plugin doesn’t seem to see them, and I have to manually open every product page and save it again to apply the SKUs. This action takes some valuable time. Am I doing something wrong? Is there a way to make this work?

Thank you in advance!
