What feature are you trying to enable by using "Enable VHF/UHF/Microwave features" on 6 meters?

The nattering message that seems to be annoying you is asking, in effect, "Are you sure you want this optional feature to be enabled?

General advice: it's usually best not to select an optional feature until you know what it does and why you might want to use that capability.
