Mileage tier rates are setup based on the Mileage (Quantity) – multiple rates are setup for the same Vehicle type under the Expense category for the Expense type - Mileage. When an expense report is created using this Expense category, when the user clicks on the drop down on the field “Vehicle type” – the same Vehicle type is listed multiple times. This was reported as a Product defect and concluded as a minor UI problem as the rate is picked correctly. But would be good to fix this display issue also in future builds.
