The ‘Rates are not accurate’ message is meant to alert you that you’re currently using the default ‘Rate Matrix’ included with the template model. However, that ‘Rate Matrix’ is not updated regularly, so it’s important that you review the matrix and update as necessary. To do this, toggle F45 to ‘Show’ and then on the ‘Rate Matrix’ tab, update the values in blue and change the value in cell B9. That should remove the alert you’re getting on the ‘Summary’ tab.
