Weldment Profile Sketch and Planes Keep Appearing

Here is the scenario.

- I create a basic weldment feature containing a couple of univeral beams based on a couple of sketches.  Showing planes and sketches are turned on and I can see the lines representing the weldment path and the weldment features.  The sketch and plane that define the weldment profile are automatically hidden

- I create a configuration of this weldment (for what ever reason) and add another weldment feature

- When I switch back into the default configuration, the new weldment feature is supressed (which I would expect) but the plane and sketch relating to the weldment profile are now visible

- This also happens when you switch to other configurations, not just the default

Why?? and is there a way to turn this off.

Thanks,

Jason
