VRM shows a far too high consumption after adding a shelly for heatpump

Since I added a Shelly to measure heatpump consumption the data in the consumption overview shows far to high values.

VenusOS 3.80-22
VRM Public link: VRM Portal - Victron Energy

Additional information:
The Shelly EM50 has been in use for about a year now.

Updated to 3.80-27 and it still shows the wrong data.
