Why is file flagged as modified when I make a different configuration active?

Working with an assembly, I find if I make a different configuration active in a component, SW tags the component file as modified. This causes minor aggregations for our PLM. The component's file content hasn't changed, so I'd prefer that SW would recognize that everything is cool and not change the file status. Anyone know a setting for this?

Thanks
