Action Adapter : Power Calculations - Not working


I am using OpenPDC version 2.4.120 . The Power calculation work without any hitch on two of my workstations. I can access the values via the historian with no issue.
However, when I do the same for the laptop, the power values are not calculated in OpenPDC (it is displayed in the graph measurement window). The screenshots for OpenPDC is attached.
Your help to troubleshoot this issue will be greatly appreciated.

Many Thanks,

Are the GPS times of the PMU data coming into your laptop GPS synchronized? I would check the status information for the PHASOR!POWERCALC action adapter to make sure it’s not discarding any data. From the console window type LS PHASOR!POWERCALC to get details.
