Why the difference between pathloss and power for different locations are not fixed

I'm currently simulating the propagation in the urban environment using Proman. In my setting, there is an isotropic antenna site with transmission power set as 10W. Intuitively, for the propagation results, the difference between pathloss and power should be strictly 40 dB (which equals the transmission power in dB scale) for all locations. I just checked that for most of the locations, the difference between pathloss and power is roughly 40 dB. However, for some locations, the difference is only 35 dB. What's the reason for this kind of non-consistency?

    Thanks for your report.
    There might be an impact if the filter options are activated.
    Please disable the filter options under Settings > Global settings > Display and Computation tabs
    and try again.
    If there is still a difference observed, please share the project with us and we will have a look.
