We're using Payment plans for a subscription service. We want CSRs to manage the payment plans in commerce manager. However, if we make any edit to the payment plan, we're unable to save, when we do we get the following error:

Validation Error: Number 1 - 'The payment total and the order total do not match. Please adjust your payment.'

The payment plan does not have any payments. We'll create a payment when the plan gets converted to a purchase order. Does anyone have an idea why this error is happening?

thanks for the help,
