You may have an Unresolved Online order somehow pulled in two payments, one for the order, and another charge from something else. However, when you try to remove the extra payment, you receive the error message: Invalid reference transaction ID.
You may notice that an unresolved online sales order was created with the same credit card details in the error message as a completed online sales order for the same constituent. You may notice specifically that both orders share the same credit card authorization code. You may not want to cancel this order because you do not want to refund the completed order on the constituents record. Please contact support for further assistance.
This issue has been resolved. If you experience this issue, please chat with support and provide the order number of the Unresolved Online Sale and the order number of the completed order.
