Where to find KiCad symbol for unidentified Uno?

If I put the physical board and the KiCad Arduino_UNO_R3 symbol side by side

it doesn't matter which way I rotate the board, or turn it over to view from underneath, the connection points are not in the same positions as in the symbol. For example, the physical device has 18 female connection points down the right hand side in the image. Neither side of the symbol has that. Am I simply wrong in supposing that the physical layout of the board and the symbol match?
