Hi,
A possible explanation?
If the SID is coded correctly in the database, it should work. I am not sure about that particular departure but I have seen similar SIDs where the first turn point is an altitude which do not look correct on the Plan page until the weights/take off data are inserted. The FMGC cannot calculate when it will be at 6000 feet till it has that information but on the flightplan page it should be able to check if it agrees with the plate. A european example is Cagliari in Sardinia where the turn points are at an altitude and then go back to the VOR, this never looks correct till all the data is inserted
