Solar Forecast unrealistic and extreme high

Hello
Since 13th of december my Solar Forcast skyrocket to absurd values (I have 7kWp and the daily forecast jumpe above 200kWh). An forcast reset does not solve the issue now I got a forecast for today of 1.1MWh see attached picture). Is there any way to get this back working as I utilise the forecast in different controle loops in node-red.
That during winter with low and fluctuating solar yield the forcast is unprecise is clear and ok, but thats around 3 magnitudes off. Is there a way of add information into the forecast process to get back to realistic values?

Are you using an mods or beta virtual nodes?
