Parameter - advanced settings - set rc to param

Hello everyone, thank you for reading it.
I would like to setting the parameters by transmitter knob. I set the transmitter chanel, and I chose the parameter what I want adjust. I set the parameter editor -> Advanced settings-> Set Rc to param…
Then set the dialog. Then Save. I see this is working, when I adjust the transmitter knob the param value is adjusted.
But when reboot the machine the set is lost. Not working. When I connected again the USB i see the setting erased, not adjust. I set again, working, but after reboot again lost.
Please help me how can I use this function.
