[Gmsh] Problem saving a 1D mesh with groups

[Miguel Segade]

Hi

I'm trying to create some groups and a 1D mesh with gmsh.  I import the
mesh from an .iges file and then I create the groups (Physical Points).
After that I create the 1D mesh and everything seems ok, the problems is
when I save it, only a cople of nodes and elements show in the mesh. If I mesh it
without defining the groups, all the mesh is correctcly saved.

Is this a bug? I'm doing something wrong?

This are the files:
