I am using Magento One Step Checkout extension by Magestore: http://www.magestore.com/magento-one-step-checkout-extension.html
Do your Store Manager Extension is compatible with this extension?

Thank you for your interest
Store Manager for Magento is intended to manage only default databases and it is not compatible with any extensions, customizations, or any other integrations of third party companies.
Actually, this should not affect the possibility to update Products, Categories and Customers, so we'd recommend you to request free trial license and check the product:
