Canon lens not recognised

I am just reviewing and re-editing some old RAW photos taken on a Canon 60D with a Canon EF-S 17-85 f/4-5.6 IS USM lens.  The camera and lens are correctly identified in the metadata for these photos, but when I go to the lens correction tab it says the lens cannot be recognised. If I then enter Canon as the make it tells me my lens is a Canon 16 mm lens, so I then have to select the 17-85 from the long drop down list.  I don't mind having to do this for one or two photos, but I have many for which I need to make this correction.
