Hi TERRYFLANNERY T
I apologize for any inconvenience caused. I've just tested it in our staging site and it works fine for us.
So please, if you have the last update of our premium add-ons, and you have made the test of deactivating all plugins except ATUM add-ons and Woocommerce, and the problem persists, I have to ask you to open a private ticket to provide us with your website credentials in order to take a look.
This is the link to open the private ticket: https://stockmanagementlabs.ticksy.com/
If you provide us the link to a staging we could make the test there, if it is a live site I have to ask you for permission to download a backup as we will need to make modifications in the stock to test.
Best Regards,
Andrea.
