Maxpower on Sonoff Dual R3

[drakkons]

hello,
I wanted to ask you a question.
i have a sonoff dual r3 with tasmota installed. I'm trying to set the maxpower option for the device. However, I note that by setting it, the option belongs only to switch 1. The option does not belong to the sum of the watts of the 2 switches, nor does it have the same value for the separate switches.
Do you have any idea how to set the maxpower option for switch 2 as well?
thank you very much for helping!
