Hi cchavarria
I apologize for any inconvenience caused.
Please, first can you make sure that you have the last version of ATUM add-ons? If you have, try to deactivate all plugins except ATUM add-ons and Woocommerce and see if the problem persists.
If it does, I have to ask 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/ticket/
And remember to make a reference to this post.
Best Regards,
Andrea.
