Zero feed-in problem

We have a problem with the EM24 and the zero feed in the ESS. The screenshot shows that supposedly 0 kWh has been fed in.

In fact, however, 6 kWh were fed in.

The system has the following components:

We use the original Victron cable for data transmission. V2.85 is used on a rpi.

We have set the mains supply to 500W on a trial basis. However, this does not prevent the grid feed-in either!

Where could the error lie?

Try changing "multiphase regulation" from "total of all phases"

to "individual phase"

We replaced the multi with another one and everything works fine with it. This means that the first Multi is working incorrectly. I'm curious to see how the repair will go...
