[Gmsh] Strange Extrude Behavior

when I extrude a planar surface (a rectangle), the resulting top surface
is a plane  too, but all 4 sides are ruled surfaces. After meshing the
cuboid I get the strange behavior like you can see in th attached file.
Two of the side meshes are tilted pyramids, one is orientated out of,
the other into the volume.

Is there a way to extrude with planar sides or to redefine a ruled as a
planar surface?
