Hello Micael - There's nothing wrong with your mesh: it's simply that
you've created several physical entities that contain the same
elementary entities. (And if an elementary entity--say, a
surface--belongs to more than one physical entity, then the elements on
the surface will be saved in the .msh file one time for each physical).
