Swap COM 2 standby not working

I cannot find a keyboard setting for swapping the com 2 standby/active

There are two “SET COM 2 STANDBY” settings, both of them have as description: “Swaps COM 2 Frequency with standby”.

Both of them don’t swap the COM 2 when assigned.

Moved to Self-Service, peripherals.

Found it again, don’t know why it disappeared though. COM2 SWAP
Still I find description of SET COM 2 STANDBY is wrong/unclear
