Bug in ADIsimPLL?

I'm using ADIsimPLL to analyze the ADF4371. I need to know the integrated jitter. When I integrate 100 Hz to 20MHz I get 72.6 fsec. When I try to integrate from 10 Hz to 20 MHz, the phase jitter entry in the report goes away.

To change from 100 Hz to 10 Hz I go to Edit / Report Options and under PhaseNoise Tab I add "10," to the beginning of entries. Under the PhaseJitter Tab I change LowFreq from 100 Hz to 10 Hz.

Once I've done this, the report has the new Phase Noise Table entry for 10 Hz but the Phase Jitter is no longer in the report.
