my current guess is that our antenna attribute is wrong for an inout port:

48   │   PIN A
  49   │     DIRECTION INOUT ;
  50   │     USE SIGNAL ;
  51   │     ANTENNADIFFAREA 0.702000 ;
  52   │     PORT
  53   │       LAYER li1 ;
  54   │         RECT -0.025 1.495 0.355 2.465 ;
  55   │         RECT -0.025 0.820 0.165 1.495 ;
  56   │         RECT -0.025 0.255 0.820 0.820 ;
  57   │     END
  58   │   END A
