Strange AC Loads calculation

I noticed my Loads tile values are incorrect. First, the drill down on the AC tile doesn’t include an output voltage and the calculation is wrong…sometimes. MP2x120 24V, sustain mode.

Tried the latest 2 beta and v.3.67 releases, same on all. I do have the serial driver installed. Same results with the gui rolled back to stock. I verified I do have actual output voltage, MQTT, Node RED, and VRM show proper volts & power but the GUI and Connect do not.

Restarting the VE.Bus system will bring back a proper calculation for a bit, but then it drifts down to zero again over a few minutes. It seems like a filter winding down? The gui voltage is still zero even after bus reset.

Switch the MP to inverting and I get stable power value, but still no voltage in the drill down, switch to ON and the power reading drops to zero.

The last pic is with the battery charging at 1.2A after switching to inverting, still in sustain mode. AC load current is lower than before?
What is the S value in MQTT?

I’m not sure where to go from here. Has anyone else seen this or have suggestions?

Update. Removed all of the modifications, support status shows clean & green.
MP 2x120V Cerbo GX & Smart Shunt as BMS.

V3.67 inverting. VictronConnect shows 120V, 0.48A, 20W. GUI shows 20W, no drill down or voltage. Is this power calculation correct?

V3.67 on shore. VictronConnect shows 120V, 0.34A, -4W. GUI shows 0W, no drill down or voltage. Is this power calculation correct?

I’m not sure what to make of the power calculations. Is the drill down missing on everyone’s MP?
