VRM Consumption Forecast completly off (zero, to large)

[spacecow]

Suddenly my consumption forecast of my system (for a normal home with solar and battery) is totaly off.
The next days the forecast ist zero altough the last days/weeks/month it was normal (between 5 and 20 kWh/day) and then there is a block with 150kWh/h for some hours.
Is there a way like for solar to reset the forecast or normalize it like for solar forecast?
Or has anybody an Idea how this could happen?

Zero forecast:

Large forecast (countinuing next day till 8 o’clock):

Thanks,
Björn
