Thanks for the hlep.
I have created a number of STARS at various airports using Captin Sim and this LEMH has been the only problem so far.  As you say, the two AIRAC entries are identical so the problem must be elswere.  
I fly the another company 747 and use this airport regulaly and have always used this aproach and the STAR is entered with no problem.

I think I must keep my old cycles in future.

Thanks again for you help.
