Problem measuring Gain Compression on PNA-X

I am not able to reproduce my Power data from my rack&stack setup.

I have attached a snapshot of a window.   My reference gain is lower then my P2dB gain, and about 5 dB lower then my small signal standard class measurement, which in turn makes my Pout lower as well.

Am i look at this wrong(the REFS21) ?

This is all CW measurement.  I also have an external 30dB attenuator (not deembedded).

OJ,  think you might be able to spend a few minutes with me in the labs ?

Thanks !
