This is what the guys at Pocket FMS have to say:

In all modest honesty I think AFS should provide a solution for those duplicate ID's; as [a] minimum pick the one closest to your current location . If the only solution is to remove FIRs then that would be uncomfortable, specially if you go fly in Europe mainland, France for example, where there are many Airfields with the same VFR reporting point ID (N,NW,S,W etc are very commonly used) .
Comments please.
