Guys!!! Pls help, I think i am going crazy soon......

I am an amateur in CFD and i am investigating a case involving solar radiation effect on the room temperature. Therefore, I start by a very simple box for testing.

I have activated the solar tracing model. After setting up the material and boundary condition, I initialize the model with standard initialization. Then, I went to look at the "Solar Heat Flux" under the "Wall Fluxes..." , the result shows zero everywhere
Could anyone pls help me talk a look at my procedures (attached) and correct me if i have done anything wrong

p.s. all boundaries are with the same materials properties and settings (i.e. Figure 3 & 4)
