Hi @kg1
Thanks for using ATUM. Generally, we recommend to use Storefront theme, however, maybe the issue it's not because of the theme and we need to investigate.
Please, can you open a private ticket in order to provide us with your website credentials? We will be able to investigate the issue in deep.
This is the link to open it: https://stockmanagementlabs.ticksy.com/ticket/
Best Regards,
Andrea.
