What is the shop or customer experiencing? The shop reports that when attempting to issue a partial refund as Account Credit for a specific item, the Calculate Refund button is grayed out, preventing the process from being completed.

What is the expected behavior? When the shop selects Refund Order > Partial Refund > Account Credit and enters the amount for a specific item, the Calculate Refund button should be active and clickable.

What error messages are there? None. The button is simply non-responsive/disabled.

Did you replicate? Confirmed. After obtaining shop permission, I followed the workflow (Refund Order > Partial Refund > Account Credit). The Calculate Refund button remained grayed out after entering the item amount.

What settings were checked? *Order/Fulfillment Tab

* The Payment Method is Stripe
