One S31 doesn't show power correctly

ESPHome
1

I have four Sonoff S31 smart plugs all flashed with ESPHome. I flashed one and then copied the configs and only changed the name and the corresponding secrets. I got all four in the same package.

One plug, ole number 3, doesn’t show power correctly. I will plug up an enterprise network switch and it will show 0 Wh used and 1 V. I know this is wrong because another plug monitors the whole rack, and I can see its overall power used go up by about 130 Wh, which is correct and what I expect. How can I fix this one plug? I have tried wireless reflashing and I’ve also reflashed it with a serial port.
