There is a awaiting contact status for this invoice. Thus no contract was uploaded during the "Add Invoice" stages. Suggest not to allow button to be enabled for invocie approval if contract not uploaded.
The upload button is disable if no contract uploaded. I suspect the issue arose due to #515 when duplicate invoice was somehow generated automatically.
