Spectrasys and Cascade P1dB Analysis Questions

I'm not getting consistent P1dB predictions from Spectrasys for a simple cascade analysis.  It is depending upon source input power.

If I use the example file from Eagleware Spectrasys titled "System Input P1dB", I get the following results:
-50 dBm input gives IP1dB of -20.557 (default)
-70 dBm input gives IP1dB of -24.073 ???

In the standard interpretation, I don't believe P1dB should change as a function of input power.  
No one else has this question
