Just noticed a curious thing; a bug perhaps?

The following lines give me an output that includes altitudes of entrances and no co-ordinates, as I would expect;

#!CAVE LIST EXPORT

export cave-list -output ./Outputs/GLMESM_SystemCaves.html #\

#  -location on

And the following gives entrance co-ordinates but no altitudes;

#!CAVE LIST EXPORT

export cave-list -output ./Outputs/GLMESM_SystemCaves.html \

  -location on

Why no altitudes?
