Losses for wider routes are not smaller when using ADS impedance creator

Hello I am evaluating keysight 2020 update 2,  I am trying to create a single ended line with return plane h=3mil, Dk=4.6, Df=0.01.  then I try to optimize Z=50 (~5.29mil) and another Z=30 (~11.37mil),

I know by theory that the loss db/in for a wider route is smaller than the loss for a narrower route,  but in this ADS calculator the opposite happens wider routes has bigger loses. Why this not happen? is this a bug or I missing something? Thanks for your help
