The French grade is probably one of the most popular trad grading systems in the world! Orco, Jonte, Piola routes all over the place, things in the picos, some stuff in the Dolomites.....
Looking at the guide, as you say, it's a sport crag, so I suspect that it's more likely that the route, which has been recently added to the database, has been incorrectly entered as trad rather than sport.
