GSX showing I am in incorrect location

[MajorMike]

I parked at Manchester EGCC Gate 209. When I tried to pushback in my PMDG QOTS II 747-400 a pop up screen said I was at JFGC Manchester helipad and offered no pushback option.
I have attached screenprints of the FS tramp which does show Manchester helipad but I appear to be parked at Manchester Airport.
I also show the Afcad when I selected GSX - Customize aircraft position.
I am presuming that it is looking at the wrong Afcad file but is there a way to resolve this?
Thank-you.

Thank-you Umberto,
That has worked.
Apologies for not having noticed that in the manual.
Regards,
Mike
