That is normal behaviour. I guess the thinking is that a Setup is generally configured and saved with reference to a specific set of instruments in a specific venue/room. Hence, a change in Setup will load a configuration that may not be appropriate for the current set of instruments and room (volume, feedback, etc...). Accordingly the Mains Out is zeroed so that the user can proceed with caution and avoid an immediate unpleasant incident with excessive volume/feedback.
