Shelly - Pro 4pm wrong kwh indication

Hello I am having issue with the shelly integration, I have a 4pm pro that is not reporting correctly the kwh consumption.
Is it a bug or is it my fault on the configuration?

I have 4 channel

channel 1 always off and but the consumption is 0,48 kwh
channel 2 I connected a lamp it report 29W but the consumption is 0,56 kwh
channel 3 and 4 are always off and the consumption is correct
