What is the difference between power probe P_Probe1.p and P_Probe1.deltav in ADS?

I ran into this problem while simulating an RF rectifier.
I used harmonic simulation (HB) in the hope of seeing the efficiency of the rectifier. When RLC components are introduced into the circuit, I can see P_Probe1.p and P_Probe1.deltav in the result viewing interface. Otherwise, I can only see P_Probe1.p.
I tried to find the answer in the ADS help documentation and the Internet, but couldn't find it, so I came here to ask for advice.

From what I tested, deltav is the voltage from power probe to global ground.
Calculated power p is probe current * deltav

Double-check your simulation setup, ensuring that all relevant parameters are properly defined.
Verify that the harmonic balance analysis settings are appropriate for your simulation.

Thank you very much for your test. I also conducted a basic simulation test today. Note that as you said, P_Probe1.deltav is the voltage at power probe 1 to ground, and P_Probe1.p = 0.5 * P_Probe1.deltav * conj(I_Probe1.i), where I_Probe1.i is the voltage flowing through power probe 1 of current.

How does your latest post relate to post #1 where you state "I can only see P_Probe1.p"? Is the orginal configuration different?
 
@FvM: With only one probe, the "deltav" result is shown as "deltav" instead of "P_Probe1.deltav"
I guess the same happens if both probes are connected to the same nets (identical voltage)
