[Gmsh] wrong maximum-values in a contour plot coming from a .med-results-file

When opening a .med-file containing vmises-stresses for 5 loadcases,
GMSH shows wrong maximum-values. I do it in this way:

- I open the .med-file with GMSH. The contour plot shows correctly the
maximum value of the worst loadcase.

- to create a plot for each loadcase with the loadcase-specific max
values, I do so: Options, highligth view (View[9]), in Tab General I
cycle throug the time steps (0,1,2,3,4). I set "Range Mode" to Custom, I
click onto "Max" (the value there should now be adjusted to the
max-value of that loadcase).

But the max-values shown in the contour range bar seem me to be wrong.
Because the differ from my printout which I made with Code-Aster. Also
creating Contour-Plots with Salome (with the same .med-file ), Salome
shows those maxima which are printed out by Code-Aster.

Strangle, the max-values of GMSH are all by a factor=1.235 smaller than
those printed by Code-Aster.

I attach the .med file with this problem:

I observe that this problem does not occur if I work with linear
elements (no additional nodes at mid-edges). So it seems the problem
occurs only with quadratic elements.

This was the Code-Aster command to create the med.-file:

Screw, only Tetraeders',

"RESTREINT" means that I printed only a part of the mesh and the
respective part of the field of vmises-values.

Can somebody please show me how to get the contour-plots with the
correct max-values for each loadcase?

Thank You
