Ok... I guess common.h is keymap_common.h in the GH60 folder? If so I think you need to change the ANSI sections to
K30, K31, K32, K33, K34, K35, K36, K37, K38, K39, K3A,delete K3B K3D, \
and
K30, K31, K32, K33, K34, K35, K36, K37, K38, K39, K3A, NO, NO, K3D, \
I'm not sure why you're trying to pretend this is a GH60, why not build it from scratch so you know how it works?
