Completing Transactions from Billing Dashboard Auto Approves Invoice.

Invoice approval rules have been defined. The Invoices are being auto approved once clicking on the "Complete" button located within the Incomplete info tile instead of going for approval to the dedicated approver.

Will removing the "Complete" button from the incomplete info tile be appropriate to solving this issue? Would the removal of the button impact the workflow of other tasks in any given module? If yes, then what would be the impact?
