In the current versions, there is no need to assign conditions this way for COM/NAV encoders.
Just assign "Com1_Mhz" to your encoder and "Com1_Pull" to its button.
That's it. While the button is pressed, the encoder will change khz instead of Mhz.
P.S. Don't use any "outside" videos (especially old ones) as guides - they are often irrelevant, incorrect or outdated.
Only information on this site can be always correct, just ask.
Note: On your screenshot I see you have some deprecated assignments and not existed parameter names. in your cfg file, why?
And, you should NOT fill your cfg file manually, use the configurator only.
