VNA Measurement Issue on VSS

Hello, I was trying to get some measurements like OIP3, OP1dB and such as on VSS. I was using a ADL8142 and connected a VNA to it. I also specified the FSTART and FSTOP as 23/31 GHz and I have added the netlist to my AMP_F. But there is a problem.

1- When all the columns and values from the netlist are available (Freq(,MHz) Gain(,dB) NF(,dB) OP1dB(,dBm) OPSAT(,dBm) RISO(,dB) OIP3(,dBm) S11(mag,dB) S11(phs,deg) S22(mag,dB) S22(phs,deg) OIP2(,dBm)), the measurements for Gain, NF and etc. are wrong compared to the datasheet. Also, the netlist data are directly from their website so it shouldn't be a problem.

2- When I delete all the columns except Gain and NF (Freq(,MHz) Gain(,dB) NF(,dB)) and measure again, they become right.

3- When I add a single column of OP1dB (Freq(,MHz) Gain(,dB) NF(,dB) OP1dB(,dBm)), they become wrong again.

Is there an explanation for this which I am missing? I am new to AWR and especially VSS and it is important for my project. Thanks!
