Negative values?

[scfigg]

Last year, I randomly started getting all of my values (such as wattage), being shown as negative. I was told I had the two connectors reversed on the wires - so I swapped the wires that they were connected to, and it started working again. As of like 2 months ago roughly, I started getting negative values again. I haven't changed any physical setup. Any idea if there's something on the software side that changed? or that I can change to start getting positive values again?

Is it possible that the voltage reference was changed or plugged into a different outlet? Even if the voltage transformer was turned upside down, this would also reverse the phase, causing negative values for the current.
