Hi Ronnie,
I'm sorry again for any inconvenience caused.
Please, I have to ask you to try to deactivate all plugins except ATUM add-ons and Woocommerce and check if the problem persists. If it does, please, we will need you to open a private ticket and 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/
And remember to make a reference to this post.
Best Regards,
Andrea.
