SAFE Punching shear design overwrites- Location type

[S_P]

Hi I'm trying to overwrite the location type of an interior column to be of "Corner" location type. I created a new model from an initial "Flat Slab" template with default settings but without drops, overwrote the location type of one of the interior columns location types to "Corner" and ran the analysis and design, however SAFE gives me a "N/C" error for punching design. Is this an error? Do I need to change other settings? Or is this not supported by SAFE? If so, when and for what can the Location-type overwrite be utilized?

Thanks,
