Right now the message's visibility is only manipulated by the signalhandlers that fire when the relevant comboboxes are interacted withdirectly.
However when their values are changed indirectly as a result of clickingthe "Defaults" or "Reset" buttons that code never runs, so the messagecan remains shown or hidden when it shouldn't.
To fix this, trigger the logic any time the relevant config file keychanges, rather than only when the user explicitly interacts with the UIelements.
