Ram Concept Horizontal Line Load

Hello, Please how does Ram concept interpret horizontal line loads? I modelled 2 shear walls between three columns has shown below and I applied 2 different horizontal line loads at different elevations. I would expect the horizontal line loads to cause moments at the base of the column/ column-mat intersection. When I checked the punching shear results, it says the moment is zero as shown in picture 1. Please why is this? However, if I convert the portion of the line load on the column to lateral load and apply that value to just the column, with the line load only on the shear wall, the moment is not zero as shown in picture 2
