Incorrect subscription frequency displayed

Issue

The subscription frequency displays an incorrect option on the order details page in Shopify. 

Environment

Resolution

You may notice that a customer's subscription frequency is incorrect on the Shopify order details and any notifications after you or a customer has made a change to the subscription frequency for an existing subscription. 

When the frequency for a subscription is updated to something that exists outside of Shopify, Shopify creates the selling plan with a default option, which causes the incorrect subscription frequency to be displayed to customers. 

It is recommended that you set your customer portal settings to Customers can only choose from the plans you set up for each product. This ensures customers can only select subscription frequencies based on the configurations you set for the product in the merchant portal.
