Load definition issue

Good day
I have developed a parametric structural model in Karamba. My main objective is to calculate the estimated structure mass by changing design parameters (such as building dimensions), However, when I change ay of the loads, the results (in term of structure mass and displacement) remains unchanged. I think there might be a problem with the pink group in my model (attached).
I used mesh load for defining dead and live loads
thank you in advance @karamba3d @matttam
