CentralHeatPump Not Always Recording Electricity Consumption

My model includes a CentralHeatPump (CHP) system acting as a heat recovery chiller. It is attached to a secondary supply loop on the chilled water (CHW) and hot water (HW) supply side and the demand side of the condenser water (CW) loop. Looking at hourly data, everything seems to operate fine; for example, the CHP is meeting what it can of the CHW load and rejecting heat to the hot water loop when there is a request for it, otherwise it rejects heat to the condenser water loop.

The issue I'm having is while it is meeting these CHW/HW loads, it does not always record electricity consumption. Therefore the annual cooling/heating electricity consumption is not accurately reflecting the work done by the system.

I'm thinking this is a bug in the object but any help you can give would be greatly appreciated!
