I apologize for any inconvenience caused.
What do you mean by 'is not dynamic'? Please, first make sure that you have the last update of ATUM add-ons, and if the problem persists, try to deactivate all plugins except ATUM add-ons and Woocommerce.
If the issue still persists, I have to open a private ticket and provide us with your website credentials in order to take a look.
